In July, Roger Waters and David Gilmour of Pink Floyd played together for the first time since 2005 at a benefit concert in England. On August 16, the Hoping Foundation posted a video of the performance that can now be viewed online.

Talk of the reunion began in 2009, when Gilmour attended a celebrity karaoke benefit concert for The Hoping Foundation.

Waters explained in a July 14 post on his Facebook page: "In the wake of that evening, someone, I think it was David himself, came up with this 'Wouldn't it be funny', idea. What if he (David that is) were to sing the old Teddy Bears song 'To Know Him Is To Love Him' with me (Roger that is), what with us having been so famously at each other's throats for years and years."

Gilmour emailed the idea to Waters, who was enthusiastic, and the two agreed to perform that song plus Pink Floyd classics "Wish You Were Here" and "Comfortably Numb" at the following year's benefit. At showtime, the duo added "Another Brick in the Wall Pt. 2."

In return for Waters's agreeing to play the charity gig, Gilmour is set to appear on one un-announced date of Waters' 30th anniversary The Wall tour. That 94-date tour begins September 15 and runs through June 2011.
