Murray was the first and last guest on David Letterman’s late-night show, and Letterman will return the favor by making a rare public appearance when Murray is presented with the nation’s top prize for humor. On Tuesday, Se[t. 14, 2016, The Kennedy Center announced the lineup of performers for next month’s celebration of Murray, who’ll receive the Mark Twain Prize for American Humor.

How do you get Lupe Fiasco to perform an encore? According to Lupe Fiasco, be Bill Murray and “force it.”

Bill Murray might be among the last people you’d expect to see at a Lupe Fiasco show, but if you made it out to his performance at the Belmont last night, that’s exactly who you saw (khakis and all).

Several concert-goers tweeted out pictures of the actor dancing along to what was apparently a show good enough to warrant a demand for an encore. Lupe Fiasco himself took to Twitter to excitedly announce that Murray made an appearance.

'Twas freezing but freakin @BillMurray came out!!! You missed it lol…
