At least one and possibly two members of Pink Floyd will perform 'Wish You Were Here' at the closing ceremonies of the 2012 London Olympics on Sunday, Aug. 12.

This information comes from English songwriter Ed Sheeran, who says he will be accompanying the legendary rocker or rockers at the big event. In an interview with Nova 106.9 (courtesy of SoulCulture) he states that so far only Pink Floyd drummer Nick Mason is confirmed to appear, and quickly clarifies that it won't be the full band -- as "they don't get on." He goes on to say, though, that "I think they're trying to get someone else."

Presumably, that would mean either Roger Waters or David Gilmour, who have performed together very infrequently since Waters left Pink Floyd in 1985, most notably in 2005 at Live 8, where the four surviving members of the group's most commercially successful lineup performed together for what sadly would turn out to be the last time. (Keyboardist Richard Wright passed away in 2008.)

Waters, at least, should be in good performing shape, having just recently wrapped up his massive 'Wall' tour by constructing the biggest on-stage "wall" ever in Quebec.
