Previously, we noted that Wilco's Jeff Tweedy will appear on the season finale of "Parks and Recreation". Now, executive producer Michael Schur has told The A.V. Club that Tweedy will be joined by Yo La Tengo, The Decemberists, Ginuwine, and Boston alternative rock band Letters to Cleo, on the episode.

The bands won't be appearing as themselves, though. In particular, Yo La Tengo will play Bobby Knight Ranger—a Night Ranger cover band that wears red sweaters in the mold of the famously irascible Indiana University basketball coach.

"The three of them showed up, they got dressed up in red sweaters, khakis, and white wigs, and they played 'Sister Christian' in front of a thousand people, introducing themselves as 'Bobby Knight Ranger,'" Schur tells The A.V. Club. "It was one of the weirdest things I’ve ever seen…and completely delightful."

The episode will air on April 24.
