Pink Floyd toured (sort of) The Wall when they released it. I think they did like a week in NYC and a week in LA (because if you're not from the US, what else matters?) I know he did it in Berlin when the real Wall fell.
I'm kinda weird I guess. I like everything before DSotM a hella lot more than everything after lot less by increasing degrees. So DSotM was Good, WYWH, OK, the rest, nah. Personaly, I think that The Wall could have been a 45 with Comfortably Numb on one side, and Run Like Hell* on the other and the world would not have missed the rest which is a lot of sobby, 'oh crap I'm so rich and being a rock star sucks' kind of stuff.
Now, if he would go out and play Meddle, Obscured By Clouds and Saucerfull of Secrets - that would be awesome.
moe. however, they have been playing very well the last year and I can't wait for their next Fillmore show.
* - oddly enough - or not - I think those are the two Gillmore songs on The Wall.
