:>of PF'

. I read in an interview that it was due to artistic differences :>with RW but I also heard that It was all about his cocaine addiction.
: Rick contributed virtually nothing to Animals and nothing to The Wall. : Roger basically got pissed that Rick expected his share of the rewards : but wasn't doing anything. Some keyboard bits were played by someone : else (somebody help me out here).
Peter Wood played Hammond organ on 'In The Flesh' and others. My guess is that Rick didn't play much on TW in general, though we all know that 'credit where credit is due' wasn't exactly the Floyd's credo at that time.
: It can't be said for a certainty : that Rick's known drug habits were the cause of his lack of musical : contribution but it's a safe bet.
Probably not the sole cause, but I'm sure they were making a valiant contribution.
