David Gilmour and Roger Waters, reunited on stage

It's what music fans have been waiting years for and probably never thought they’d see it happen – the dynamic duo behind Pink Floyd, David Gilmour and Roger Waters, reunited on stage. But attendees at the Hoping Foundation benefit in England were treated to the surprise reunion, as the two played a four-song set including “Another Brick in the Wall, Part 2,” “Comfortably Numb,” and “Wish You Were Here.”

The appearance was a surprise, as the two haven’t been on the best of terms since the band’s hey day. In fact, Gilmour turned down a chance to tour with Waters on his 30th anniversary The Wall tour earlier this year. This was the first time Gilmour and Waters have appeared together on stage since 2005.

The two helped raise more than $520,000 for the Hoping Foundation, which assists young Palestinian refugees.
