Dave Gilmour joined Roger Waters onstage for “Comfortably Numb” during Waters performance of The Wall at London’s O2 Arena last night (May 12, 2011). They were later joined on stage by Nick Mason , marking 30 years since they last performed The Wall in London.

Great footage of the performance!

Here’s Roger bringing David Gilmour and Roger Mason back out on stage for a performance of “Outside The Wall”. Gotta love the guys genuine embrace and camaraderie on stage together and the heartfelt words Roger shares!! This is a great rock moment.
