Pink Floyd’s David Gilmour joined Ben Watt on stage at London’s Islington Assembly Hall for a performance of “The Levels,” where the legendary guitarist played pedal steel guitar. Gilmour stuck around for another song—“Young Man’s Game”—where he played electric guitar.

Gilmour appeared on Watt’s album Hendra released April 14, 2014. In addition to Gilmour, ex-Suede man Bernard Butler also sat in on “The Levels” during the show as well.
