Watch David Gilmour and David Bowie Perform “Comfortably Numb”

Surprisingly, David Bowie only made one appearance at the prestigious Royal Albert Hall in London throughout his whole career. Even then, it was only as a special guest, and it was for a unique two-song encore duet with David Gilmour of Pink Floyd.

More than five hours of video from the 2006 gig documenting David Gilmour’s version of Pink Floyd playing at the famed venue can be seen in the concert film Remember That Night: Live At The Royal Albert Hall. Backstage, Bowie rehearsed two Floyd songs with Gilmour’s band before his cameo appearance: “Arnold Layne,” from their 1967 first single, and “Comfortably Numb,” from 1979’s The Wall. The singer was seen chatting pleasantly with a camera team capturing what would be the concert film, so it’s safe to assume he wasn’t nervous about performing again two years after the forced cancellation of his Reality Tour in 2004.

In the brief chat, Bowie expressed enthusiasm for a plan to playfully humiliate Gilmour behind the scenes. “I’d say I’m a big Pink Floyd fan,” Bowie said, as Gilmour joined in on the conversation. “The first time I saw them, my parents dragged me along when I was six or seven. I saw them at the Marquee I think.”

Gilmour laughs, knowing that Bowie was in his teens when Pink Floyd first started to make rounds in the music scene. “Six or seven, I think not!” Later that night, Bowie made a memorable appearance onstage with the band, and the audience could tell how much the two musicians admired one another.
