Regulars to the Roger Waters official Facebook page have long enjoyed the videos that have been posted there from time to time. We share these videos on the Brain Damage Facebook page too, to help spread the word.

This evening, a new video has been posted which is an absorbing, five minute look at the surprise appearance of Nick Mason and David Gilmour at London's O2 Arena, a year ago virtually to the day. The video clip shares David's arrival, a pre-show meal, rehearsals during the day for the Comfortably Numb and Outside The Wall spots, and other aspects of their get-together.

The screenshot here gives a flavour of the clip; to see the video in full, click here [UPDATE: or look below!] You may need to sign up to Facebook to view it; our hopes are that this will form part of the footage being prepared for the eventual DVD/Blu-ray release we're hoping to see in the not too distant future...
