Discussion point - support bands...

Razorlight?

Metallica/Extreme/Def Leppard/Guns N Roses/Spinal Tap/Bob Geldof?

Hmmm. Interesting question. I'm honestly not sure.

I'd probably say yes for Razorlight but no for the others since they were at the tribute concert.

Controversial...I'd go for all of them, but with a suitable disclaimer to fend off the inevitable arguments.....or we could just ignore them!
