"I turned to look, but it was gone"

Somewhere, David Gilmour is still doubled over laughing like hell. They reunited for Live 8 a few years back, performing together as Pink Floyd for the first time in two and a half decades, but he and Roger Waters had one of the most acrimonious splits in pop music. Moreover, while he's still got the rights to the name, Gilmour also has some impressive friends willing to step up when he needs a vocalist.
