Pink Floyd Back Together For A Moment.

The surviving members of Pink Floyd reunited on stage Thursday night at London's 02 Arena during a stop on Roger Waters' "The Wall" tour. This was only the second time that Nick Mason, David Gilmour and Waters have played together in the last 30 years. As the crowd went absolutely insane, Waters and Gilmour performed "Comfortably Numb" with David playing his epic solo on the top of The Wall as he did on the original 1980/81 tour. During the finale of "Outside The Wall," Gilmour returned to the stage alongside Mason, who played a tambourine. Last July, David promised that he would play the song during one of Roger's shows, but drummer Nick Mason's involvement was kept a secret. They last performed together at Live 8 in 2005.
