Wilco's Jeff Tweedy covers Black Eyed Peas' "I Gotta Feeling"

(CBS) - A Chicago book release party got the genre-bending thrill of a lifetime when Jeff Tweedy of Wilco showed up to play some of the Black Eyed Peas' greatest hits. Dan Sinker's "The F***ing Epic Quest of @MayorEmanuel" - based on the fake Twitter account of mayoral candidate Rahm Emanuel - was the focus of the evening, but the highlight has to be Tweedy's performance of that modern-day-classic, "I Gotta Feeling."

As Time Out Chicago reports, Tweedy played several of the Black Eyed Peas hits, as well as a spoken-word rendition of lyrical monstrosity "My Humps." If it was half as hilarious as the clip of "I Gotta Feeling" above, it must have been a great night.
