Behind the scenes footage emerges of Pink Floyd's 2011 reunion
It was a year ago that David Gilmour and Nick Mason joined their former Pink Floyd bandmate Roger Waters on stage during a performance of his The Wall tour.
Waters was playing a show at the O2 Arena in London when the two unexpectedly joined him. Gilmour made an appearance during the song Comfortably Numb, while Mason joined the two closing the show with the song Outside The Wall. It was the first time the band had reunited since 2005 when Pink Floyd, including the late Richard Wright, performed at the charity event Live 8.
Backstage footage from Waters O2 Arena show has now been released, featuring the former bandmates interacting and rehearsing.
