You haven’t heard the Black Eyed Peas until you’ve heard the Black Eyed Peas as performed by Jeff Tweedy. At a Chicago party last year for Dan Sinker’s book “The [Expletive] Epic Quest of @MayorEmanuel,” the Wilco front man covered “I’ve Got a Feeling” and “My Humps” with his tongue planted firmly in cheek.

Tweedy smirkingly deconstructed the former for acoustic guitar, while the latter was read as a spoken-word poem (complete with dramatic phrasing, eye rolls and looks of confusion). When one lyric puzzled him, a crowd member shouted out to explain it and Tweedy looked down at him, shook his head and deadpanned: “I’m sorry you know that.”

Wilco, which headlines at Wolf Trap next week, hasn’t always been known for its sense of humor, but as Tweedy’s aged, he’s taken a much more comedic approach to his stage banter — and even his songwriting.

On 2009’s self-referential “Wilco (the song),” Tweedy asks his fans, “Do you dabble in depression?” before offering a prescription: “Wilco/ Wilco/ Wilco will love you baby.” Laughter, after all, is the best medicine.
