1. I thought they hated each other

Surprised they would play together under any circumstances.

2. It was a one-time shot, as I understand.

I don't know the full story, though. Maybe someone here does.

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.

As he did on the original 1980/81 tour, Gilmour played his epic solo on the top of the Wall. Last July, Waters promised that Gilmour would play the song during one show on the tour, but drummer Nick Mason’s involvement was kept a secret. They last performed together at Live 8 in 2005. Original keyboardist Richard Wright died in 2008.

Confirmation of Gilmour’s appearance hit the web hours before the reunion on Gilmour’s official fan blog. “I should also remind you that tonight is most definitely a one-off,” the blog notes. “David is not repeating his special guest performance at a later occasion, I’m sorry to disappoint those of you with fingers crossed and tickets for later shows.”
