He was an important part of the band. More crutial to their sound than a lot of us suspected. I used to listen to a lot of Pink Floyd until they got very popular. It was a nasty habit of mine back then. Dropping bands because other folks liked them. I may be one of the few people who's copy of "Dark Side of the Moon" was only played once. I worked in a record store at the time and it was on our turntable all day long. That would take the joy out of any recording.
