Hi Aphex, I know I've annoyed you in the past criticising Pink Floyd and I apologise for that.
I fully understand your dilemma and don't envy you having to make a choice. I'm trying to imagine one of my favourites like Weather Report or the classic Yes line up being on at the same time as the match and I've decided I would sell the tickets (if poss) and watch our historic final and us lift THAT cup !!
My belief is that is you go to the concert you won't really enjoy it. (thinking constantly about thousands of Blues riveted to it)..
Hope that helps in some way mate. But I know how much you love PF so must be difficult.
In some ways it's be like
@Mad Eyed Screamer having to choose between eggheads and the CL final. (or yes, a Morrissey gig) :)
