In my opinion, Syd Barrett in his time was a damn good musician, he was a Crazy Diamond, a genius. I mean what would have been of Pink Floyd without him. To be honest, everything they did was great really great. And I mean, changes in bands are great: first was the Syd's era with The Piper At The Gates of Dawn, and all their eraly work, then he left. We got different album. Excellent albums. From Meddle to DSOTM, Saucerful of Secrets to Wish You Were here, all of them different but with kinda same concept. Then the 3 Water's era albums: Animals, The Wall, The Final Cut. The style changed and it was very notable. First 2 very good. Who hasn't ever heard that some people identifies Pink Floyd with The Wall. Then Rog leaves the band. We come to end with the Gilmour Era with A Momentary Lapse of Reason and The Division Bell. One of my teachers consider AMLOR her favourite album. And here we have, another change. To my opinion they werent at their original level but still were great from many points of view. All of this thanks (partly) to Syd. And he has never left the band. He was on the Piper at The Gates of Dawn as the Leader. Then he took a little part in Saucerful Of Secrets, he was remembered in DSOTM's Brain Damage, and the album dedicated to him, Wish You Were Here. In The Wall, the story takes some parts of Syd's life (Roger's too). And in the Live 8, ya remember great Rog's words, at the beginning of The song Wish You Were Here?:

"It's actually quite emotional standing up here with these three guys after all these years. Standing to be counted with the rest of you. Anyway, we're doing this for everyone who's not here, but particularly, of course, for Syd."

See. Syd will always be part of Pink Floyd. Roger Waters, might have fought against the other 3, but he will be also part of The Floyd. Rick, Nick and Dave too.
And I Love all of Floyd phases in fact!
