Regarding Saara singing for the UK - I think we might just be desperate enough to try something like that.
I am not a great believer in flags of convenience. Yes, yes, Celine Dion and Switzerland, but Celine Dion is Celine Dion, she's a completely different league. It pains me that the last UK winner ever isn't actually British but at least the Blessed Katrina had lived here since 1976, she had properly gone native, she had a British band and the song was written, produced and arranged by Brits. We are never going to replicate that re-flagging somebody now, nobody actually agrees on what being British is anyway. It's also quite a different thing when you represent somewhere you don't have that much of a connection with, Saara, as good as she would be for Finland and as much as she will mature and grow as a performer in the coming years, does not represent anything distinct from this country or its immediate neighbours, our traditions and what's going on in our country in the broader sense whilst having enough there for other people to connect with a la ' Molitva', never-mind '1944'. Re-flagging a creative team to stage it (a noticeable BBC weakness) or bringing in an outside song-writer with a proven track-record to add a little universality is about presenting those themes - but the themes have to be ours to start with to feel real. The artist is the Ambassador for their nation - what does it say when the artist doesn't even come from the neighbourhood of that nation?
Say we do borrow somebody for example Scandinavian, they still need to be content with whatever crap the BBC is prepared to provide for them vis a vis staging (I can't see any real professional with a wish to do well being so) and it'll be very obvious the minute they opened their mouths to speak how desperate we are. Re-flagging doesn't always work (Nana Mouskouri sang for Luxembourg of all things in 1963 and she was only 8th and lets not even mention Gina G). That's before they contend with the fact the fact its the UK with the baggage that comes with that, after-all Theresa May will be knee-deep in spectacularly falling out with most of the rest of Europe a la Brexit next May (necessitating us being very nice to such paragons of democracy as Russia, Belarus and Azerbaijan, for points, ironically Ukraine doesn't often give us much) and therefore we are looking at a very poor point-score indeed barring a miracle.
I am not completely convinced that it would not be a great idea for the BBC to drop-out for a few years after Brexit and indyref2 is done with and come back when we've got our s**t together as a country or broken up therefore have a bit more of a sense about what the hell we are sending somebody to represent in the first place and we maybe have a reason to start caring again or just don't even bother sending half-assed attempts taking up a slot Bosnia and Herzegovina would have killed for and then end-up embroiled in the inevitable "we're not in it so we refuse to pay for it anymore" bollocks that will emerge.
Anybody else notice the two-pronged irony that if Ireland were to go with Ghaeilge language lyrics (one of three P-Celtic languages along with Gàidhlig [Scots] and Gaelg [Manx] - think Russian and Ukrainian, different languages but somewhat mutually intelligible) for their second JESC entry then the only country containing any people that can sort of understand them (57,000 Gàidhlig with some fluency, 87,000 any knowledge) aren't in it anymore? And that the Irish might well be actually taking a page from Eastern Europe's playbook and trying to make their own culture part of their entries whilst we get blander and blander and blander? They have had a bigger fall even than us, from the Kings of the Contest to struggling to qualify year after year and yet they are still trying and engaging further with the Contest and its concept. Embarrassing for us really.
Saying that, I'm not a fan of the concept of JESC. It is a big ask for often young kids upon whom so much is being expected (poor Sofia Rol from Ukraine, what pressure must she be under to make it a twice-in-the-row black eye for Russia?) and it is potentially exploitative, but at least RTE have a bit of cultural pride and haven't given up like the BBC.
