It's not going to take much to be the highlight of the Diana Concert, so Tom Jones has probably got it nailed: he's doing a full-band cover of I Bet You Look Good On The Dancefloor:
"It's a great song and I wanted to do it as a surprise for the Princess Diana concert. I haven't been in touch with the lads about it but I hope that they like it."
Tom Jones has been in showbusiness for three hundred years and still thinks you can tell the 3AM Girls about a "surprise" and not have them spoil it.
The Girls are calculating the likely outcome, and they see good things in the future for the Arctics:
They're already the band of choice for politicians to drop into conversation, so it's not entirely clear who the 3AMies think they're going to be broadening their support out to now - the dead?
Nor, of course, have they calculated the risk that this sort of "tribute" could undermine their core support as the Arctics become ever more tainted with being "Gordon Brown's type of thing."
