I saw this in Malmo in 2013 and it was pretty incredible how fast the set changes were done. The other thing you don't see is just how close the cameras are to the performers.

> Reddit style drive by snark doesn’t work as well here imho.

Isn't this the only snark and drive-by comment around? I think it's more interesting, just as I think a pit stop change is more interesting in F1 than most of the race itself.

Den_VR•5h ago
I’ve been a fan for almost 18 years, ever since some euro friends were talking about the voting system on IRC. Love the intersection between culture and geopolitics.
isoprophlex•5h ago
What politics? Saying or doing anything political gets you mad shade thrown your way, a lot of bad press, up to expulsion.

I get that the big scrutiny against overt politics is something political in itself, but...

To me the strictness towards the presiding mainstream opinion, the forced harmony, makes it less interesting.

mrtksn•5h ago
It's not what they say on the stage but how voters from different countries behave.

UK: 0 points total

Cyprus: 12 points from Greece

Azerbaijan: 12 points from Turkey

San Marino singer: A Turkish guy sings in English

Armenia: the song is in English instead of Armenian

It gives you a clue on what's going on in every country. How nationalistic they feel this year, are they fixing their issues with their arch enemies, are they opening up to different cultures, do they feel part of the community, is everybody still annoyed by the Brits and did they took the event seriously enough to send a good song etc.

cjrp•4h ago
The separate public and jury votes does now help with that, a bit.
Freak_NL•5h ago
And yet the event is full of politics. From the voting cliques and countries favouring specific allies, to lyrics with hidden (or not so hidden¹) messages, it's everywhere. A lot of it is on a meta level though, leading to an event which taken at face value seems devoid of politics.

1: Georgia's entry in 2009 was called “We Don't Wanna Put In”…

mytailorisrich•3h ago
No politics but Russia is banned...

I think that it is rather as you suggest in your last sentence: There is strict "correctness" enforced, which is how things work in the EU in general.

Keyframe•4h ago
always has been. Eurovision almost each and every year had two streams of interest - contest itself and the technology and logistics behind it. I vividly remember the whole 1996 big talk around virtual stage tech by Silicon Graphics https://tech.ebu.ch/docs/techreview/trev_268-hughes.pdf Their brand was even prominently displayed and mentioned before and during the live event.

gbalduzzi•5h ago
I know this is not the right place for this but english is not my first language.

How is "have" the correct verb here? Shouldn't it be "has"? Like, the crew is the subject, and it has 35 seconds.

I'm trying to understand what I'm missing here, because I'm sure BBC did not make a mistake

BlindEyeHalo•5h ago
This might help: https://www.writingclasses.com/toolbox/ask-writer/are-words-...

In short:

When you’re referring to the collective noun as a unit, treat it as singular:

The band lost its spot in the top ten this week. When you’re referring to the individuals within the group, treat it as plural:

The jury had to sign for their ID badges.

gbalduzzi•5h ago
In Italian we don't have this distinction, when we use a collective noun we always treat it as singular (unless there are multiple collection, like multiple crews). Thank you for the explanation
mon_•5h ago
Doesn't your advice contradict the BBC's phrasing? Collectively, the band lost its spot in the top ten. And, collectively, the crew has 35 seconds to prepare the stage for the next performer.
rsynnott•4h ago
I think this is to some extent a British English vs US English thing; it's certainly more common to treat words like crew/company/etc as plural in British English. The linked article is being overly prescriptive, though. Both are basically fine.
StevenWaterman•5h ago
Both "has" and "have" sound ok to me here as a native speaker.

Both of these can describe the same event:

- The cows have 10 seconds to enter the field

- The herd has 10 seconds to enter the field

In the case of "crew", the word can either mean

- The people who are part of the crew (like "the cows")

- The crew as a collective unit (like "the herd")

Which is why both sound ok

OJFord•4h ago
You would have to say 'which has', but then yes it works (and is more correct than 'who have').
m2fkxy•5h ago
it depends on what flavour of English you speak. British English for instance tends to use plural for collective nouns.
pfortuny•5h ago
This is a place where uou can use either. There is IIRC a letter of JRR tolkien where he discusses this very issue. "The crew" can be thouth of as "a set of people" (so you can say The crew has) or "severa people" (so you can say "the crew have").
pipodeclown•5h ago
'Crew' implies that it is a group of people doing this and therefore they have 35 seconds. You can reconstitute the sentence to check what you should use. In this case you could say in your head:" the crew as a team check the video feed. They have 35 seconds to do this." If this was referring to an individual it would be: "Peter checks the video feed, he has 35 seconds to do this."
eu•5h ago
as a plural noun, it refers to the individuals part of the crew. similar to people, flock
christudor•5h ago
If a noun denotes a group of people – even if it's technically a singular noun – it's okay (but not compulsory) to use a plural verb.

The sentences 'Real Madrid have performed well this year' and 'Real Madrid has performed well this year' are both grammatically acceptable, and probably used roughly the same amount.

A related example is the word 'none' (= 'not one'). Technically it should govern a singular verb (e.g. 'None of the players is good enough') but you'll now see it a lot with a plural verb (e.g. 'None of the players are good enough').

poizan42•4h ago
"none" is saying something about all of the players, so how would that be singular? The word "none" is always used in a plural context, like if there is only one player then you won't say "none of the player"
christudor•2h ago
I'm talking about the verb that follows 'none', not the noun.

'None of the team was [singular] prepared' and 'None of the team were [plural] prepared' are both correct.

aitchnyu•5h ago
I once read a Wikiepedia article starting with "Pink Floyd are..." and immediately hit edit. I saw a banner comment saying its correct according to British English. Since then I've noticed lots of "Company are...". I also wonder why India uses "Company is...". My guess is Britain adopted it after Indian independence.
OJFord•4h ago
It's often proscribed, many style guides say 'the company is/has', sort of de-personifying it to the entity rather than the people that work there.

I think it's an Americanizm to say e.g. 'Apple have released a new iPhone'.

foldr•4h ago
No, it’s actually more common to do this in British English than in American English, so it’s a “Britism” if anything.

https://scholar.google.com/scholar?hl=en&as_sdt=0%2C5&q=Brit...

CoastalCoder•4h ago
Even native English speakers disagree on this.
senko•4h ago
Using plural for companies, orgs or teams is common in British English.

For example "Apple have released a new iPhone".

Thorrez•4h ago
Ok:

"The crew who have..."

"The crew that have..."

"The crew which have..."

"The crew that has..."

"The crew which has..."

Not ok:

"The crew who has..."

The reason that last one isn't ok is that "who" refers to a person or people, not an object. "Crew" can either refer to a singular object or a plural group of people. Put together, "crew who" must refer to a plural group of people, so needs a verb that matches plural.

idw•4h ago
Sometimes the BBC does make mistakes but this seems to fit their style guide:

"Treat collective nouns - companies, governments and other bodies - as singular. There are some exceptions: ... Sports teams - although they are singular in their role as business concerns (eg: Arsenal has declared an increase in profits) Rock/pop groups"

So treating a crew, like a team, as plural makes sense.

https://www.bbc.co.uk/newsstyleguide/grammar-spelling-punctu...

Both approaches are regularly used, so it is now more of a style choice, hence being in the style guide.

The Economist style guide says Brits are more likely to use plural and Americans singular but writers need to make a judgement in context: https://www.economist.com/johnson/2010/09/20/style-guide-ent...

I'd really love an alternative broadcast which shows the set changes rather than the postcards, I'm sure the people making the postcards are very good at what they do but they're almost designed to be as bland as possible, I'd much rather see a well oiled team perform crazy feats to get the stage set.

> I'd much rather see a well oiled team perform crazy feats to get the stage set

Not quite the same, but I witnessed a performance of Jeff Wayne's War of the Worlds where there was a complete failure of the stage systems about 15 minutes before the end. All the audio-visuals died and the mics cut off, screens died, animatronics went still, complete silence on the stage and only ambient light.

For about 10-15 seconds there was stunned silence on the stage and then one of the drummers in the orchestra started drumming his part again. A couple of the other musicians joined and quickly there was music. From our seat we could see the stage's equivalent of mission control - three people who'd been quietly sipping their coffee while the playlists unfolded. They went into overdrive like movie hackers trying to enter some system before the corporation goons reached them. They quickly got the audio side back and then worked on the lights and screens. They left the giant Martian war tripod to last but even that was moving within a few minutes. It was one of the most impressive system recoveries I've seen.
