Meant to say also, the fact that Graham Norton knew nothing about the Eurovision Young Musicians trailer indicates to me that he hadn’t bothered to attend either the jury final or the family show earlier in the day. At both shows the final is run through from start to finish and the inserts and adverts are all included. Also seems to suggest that he doesn’t bother to attend the daily commentator briefings.
'Doesn't bother' is a little harsh. It's more likely to be a case that he can't. Unlike most countries the BBC split Semifinal and Final commentary duties between two teams, and Graham has a chat show to record and a radio show to make. It's not a case of 'doesn't bother' more a case of 'can't' isn't it?
Graham's commentary is always pretty entertaining, and he does a pretty decent job. I think his comment on the Eurovision Young Musician trail was more that it told you nothing in, and of, itself - not that he didn't know anything about it. The EBU keep shoe-horning in JESC and other promos in to the final (last year I think it was an EBU choir competition?) that really don't work...
