I stopped reading after six posts. Just another day at the opinion factory.
I do however agree with the second post, viz:
Waters was Pink Floyd. Gilmour admitted as much in the Mason book when he said that Roger was the one who stayed all night, did the writing on the fly, got the job done, while he (Dave) and the others went home nice and early for a hot dinner and foot massage. David is a talented guitarist and vocalist who gave great gifts to the sound, but make no mistake, Roger is the reason that the 70s Floyd albums are great, while the Gilmour "Floyd" albums are nice pop music schlock. There is NO debate here. Ole Rog was the man, while the boys played their parts as rock stars. You take Waters out of the 70s albums and you'd have another 5 or so "Momentary Lapses" on your hands. What a nightmare that would be.
