Aberdeen Uni, 1979. You had to be there.

RS, Pink Floyd, U2 used to make the biggest show on the biggest stage. Quite impressive.

However, one of the best surprises I ever saw was George Clinton.

Great to see the Iceman making someone's best live act list

I am not sure about best or what, but the most fun I had was at the V Festival a few years ago when the Scissor Sisters were performing and Franz Ferdinand came on stage. Followed by some weird inflatable muppet looking characters.

I am struggling to remember the name of the band a few years ago that used to use those kinds of muppets/puppets but they were similar ones used by the Scissor Sisters.

I have probably been to others that I liked more, but that was fun.

Oh, I fell asleep at a Smashing Pumpkins concert when I was 16. That was memorable.

I wouldn't say it was the greatest, but I was knocked unconcious by a beer can (full) at the Red Hot Chili Peppers concert at Hyde Park. Not the best live act but again, it stood out.

Springsteen 1979, Lynard Skynard 1976, Robert Randolph and the Family Band any time they play.

Every single time I see them, I think its nine or ten times now, they are absolutely mindblowingly exceptional: Wilco of course.

Sufjan Stevens before he added all the bothersome trumpets and twang.

So Truckstop, generally bands that you knew first before they got famous, and only if they played in small intimate unknown venues?
