Well funny thing is if Roger Waters was not the flux that kept the tunes flowing why did pink floyd hire a bunch of writers to whip up all those tunes for the division bell cd. And why did it sound like a remix of the wall.??? I also believe that the main idea for the wall was water,s idea althought in any band there is going to be some input from the other members. If you do not want to purchase the dvd you should try to borrow a copy. The band line up is made up of members of claptons band as well as others that make it a joy to watch. And by the way i am a big fan of David Gilmour and his guitar tone is to die for.
