No, it's not a bad trip: the Muppets really did perform live in San Francisco.
Dr. Teeth and the Electric Mayhem performed a five-song set at the Outside Lands Music and Arts Festival, NME reported.
The show started with "Can You Picture That" from "The Muppet Movie" and wrapped up with a Beatles classic, "With a Little Help from My Friends."
After the show, Animal and Floyd posted a selfie with fans behind them.
The video was posted to YouTube.
The Muppet band also performed "San Francisco" by The Mowgli's, "Home" by Edward Sharpe and the Magnetic Zeros and "Ophelia" by The Band, The Huffington Post reported.
