The band were featured in one of the sketches as a Beatles cover band called Hey Dude. At the end of the sketch -- which starred host Joseph Gordon-Levitt and cast members Jason Sudeikis, Bill Hader and Kenan Thompson -- Mumford and Sons led the crowd and cast in a singalong of The Beatles' hit song "You've Got To Hide Your Love Away." (Video of this sketch is not properly available online due to music rights.)
