For an interesting perspective on Eurovision, Look up the Band 'Georgia Wonder', and their Eurovision experience. It basically tells how they were invited to take part as an act, but then the powers that be attempted to control what they did, and give them a song that wasn't one of theirs to sing for it. I think it shows that we should definitely stay in the Eurovision, but we need to be more experimental. Just do whatever, treat it as a chance to show off some unusual musical talent that resides in the UK!
