Wilco frontman Jeff Tweedy performed a handful of Black Eyed Peas covers as a weird joke last night in Chicago at a release party for The Fucking Epic Quest of @MayorEmanuel, a book penned by Punk Planet founder Dan Sinker. In this video, Tweedy plays a surprisingly good and funny rendition of the Peas' massive hit "I Gotta Feeling." He's a bit embarrassed and the performance is entirely ironic, but there's no denying that the particular lived-in sound of Tweedy's voice sounds great when he does the song's big chorus hook.
