Floyd reunites for recent London concert with Roger Waters.

This is a great piece of amateur video of a recent Roger Water's concert in London, with the on the wall guitar work of David Gilmore. Really incredible stuff that just knocked out the audience. 

Rolling Stone: The surviving members of Pink Floyd reunited onstage tonight at London's 02 Arena during a stop on Roger Waters' Wall tour - marking only the second time that Nick Mason, David Gilmour and Waters had played together in the last 30 years. 

Waters and Gilmour performed "Comfortably Numb" as the crowd at the arena went absolutely insane, and during the finale of "Outside the Wall," Gilmour returned to the stage alongside Mason, who played a tambourine. Watch a fan-shot video of "Comfortably Numb" with Waters and Gilmour below. (Check out fan photos here.) 

Waters says he's interested in a brief Pink Floyd reunion tour, but Gilmour refuses to even consider it. Just this past week Rolling Stoneasked Mason about the possibility of a reunion. "There are absolutely no plans," he said.  "But Live 8 was fantastic. We did something for other people, but we also proved that we could all work together again. I'm really pleased that my children saw that. I would have thought that could be regenerated at some time. So I live in hope – but that's no reason to put it out on Twitter that 'Nick Says Band to Re-form!'"
