Have to agree with those who say Waters was the heart & soul of PF, despite his politics (which I loathe). Gilmour may be a great guy, but he was abolutely wrong to keep recording and touring as PF after Roger left. The music on those albums is largely inferior to the earlier work, IMHO.
Solo albums - loved Pros & Cons and Amused to Death (which despite its liberal bent, has some good insights on the celebrity-worship culture which has permeated) and was so-so on KAOS. Saw Waters on tour for both KAOS and Amused - two best shows I have ever seen.
Also agree on Animals, my personal favorite PF (despite a completely anti-capitalist message).
I find it amusing that Waters & Clapton could tour together and have problems selling 10,000 seats...
