I remember the Momentary Lapse of Reason tour when they had Gary Wallis over-playing programmed drums & percussion while standing up the entire set in that huge drum cage... while Nick was left barely playing at all. It was sad to see. By The Division Bell tour they had dozens of drums between them! Mason said, "Gary Wallis and I ended up with thirty-odd drums, twenty pads, forty-odd cymbals and innumerable other bits of junk bolted to the drum risers, an installation that should have qualified us for the Turner Prize." Joey Waronker has been doing a fantastic job on drums with Waters on Us+Them tour + album.
