Ezra Koenig joined Chromeo during their gig at Governors Ball last night for a brief performance of Vampire Weekend's "Cape Cod Kwassa Kwassa". "There's this guitar riff I like to play sometimes," said Chromeo's Dave 1, playing the "Cape Cod Kwassa Kwassa" riff a couple of times. Then, Koenig walked on stage: "Hey man," he joked. "Dave, I showed you the riff, man. It's really not that hard." A performance of the song followed, which led into Chromeo's "Bonafide Lovin".
