Roger Waters, David Gilmour, and Nick Mason, the surviving members of one of the most influential rock groups of all time, Pink Floyd, reunited Thursday night on stage to perform 'Comfortably Numb' at London's O2. They say that this ever happening again is unlikely. Check out the whole thing after the jump.

This was an emotional moment that will forever go down in history for Pink Floydfans. I am a huge  fan, so just watching this video brought tears to my eyes. To see these  guys on stage again and at peace with each other was truly amazing.  We are so lucky that we have the technology that we do that allows us to be a part of things like this. Yay for YouTube!
