Danger Mouse, one half of Broken Bells, first found fame for mashing up Jay-Z with the Beatles on the bootleg release The Grey Album, and last night on Letterman, he went back to his roots. Broken Bells were the first band to perform on Letterman’s Beatles week, commemorating the 50th anniversary of the Beatles making their American debut on The Ed Sullivan Show, in the same theater where Letterman tapes. On the show, Broken Bells covered the starry-eyed early Beatles classic “And I Love Her” as a vaguely psychedelic lope. And to set the tempo, Danger Mouse chopped up tiny drum clips from Ringo Starr, with accompanying video, and make breakbeats out of them. Watch the performance below.

Broken Bells’ album After The Disco is out today on Columbia.
