Watch: David Gilmour join Roger Waters to perform "Comfortably Numb"

David Gilmour in his younger days

I've long been upset that the surviving members of one of the greatest rock bands of all time can't put their differences aside to play at least a few dates under the Pink Floyd banner. Not that I'd be able to afford tickets to such an event. But the fact that both Roger Waters and David Gilmour have endlessly been touring the past few years (either to play full Pink Floyd shows or incorporate their songs into their sets), often simultaneously, and often with drummer Nick Mason, it's just pretty aggravating at this point. What's even more annoying is when Waters and Gilmour do put their differences aside, like they did at Live 8 in '05, like they did last year, and like they did last night in London, when Gilmour joined Roger Waters onstage to perform to classic Floyd tune, "Comfortably Numb" during Waters' performance of the Wall at the O2 arena. It's just a fucking tease!

Didn't mean to get all worked up, but check out the performance below the jump. I find it rather amusing that David Gilmour is about 100 feet away from Roger Waters the entire time, and I wonder if that's symbolic of anything or that's just where they thought it would look cool. Don't expect this to happen again anytime soon (read: this will happen again sometime soon and it will fucking irritate you), Gilmour's website reads, "David is not repeating his special guest performance for a later occasion." Bummer.

Last night's performance...



Here's where Gilmour and Waters reunited last year for charity...



Pink Floyd's only true reunion at Live 8 (albeit for 4 songs... and without Syd Barret, obviously)
