Earlier this week, one of those ‘only in Los Angeles’ moments took place at the intimate confines of the Hotel Cafe — as John Mayer booked a surprise acoustic gig as he prepares to release a flurry of new music in 2017.

At the gig, which was obviously very sold-out, comedian Dave Chappelle happened to be in the room and joined Mayer onstage for a few spirited covers, one of which was Nirvana’s “Come As You Are”:

They also joined together for a rendition of a Tom Petty & the Heartbreakers’ classic, too:

Y'all they did free falling together too 😭 #JohnMayer overload today because last night was a dream 🌙
