I agree Prophecor,
I went to an imitation Pink Floyd in Minneapolis last year (Australian Pink Floyd? or something like that.) It was actually awesome, very moving, (despite no fatties there, either.) I think they did a lot of work to make it "just like the original" complete with the backup singers, film show, balloon, and everything. I hate to say, but I liked a lot of that concert better than the David Gilmour.
Except the lights at David Gilmour. they were just really awesome. Plus his guitar playing was louder and somehow right on key (no I'm not a music person at all, but it somehow lulled me into a trance (ie: I fell asleep.) (again, contact high?)
