British folk quartet Mumford & Sons stole the show from host Joseph Gordon-Levitt on Saturday Night Live. The group, featuring lead singer Marcus Mumford along with Country Winston Marshall, Ben Lovett and Ted Dwane, gave a spirited performance of “I Will Wait” backed by an enthusiastic brass section. They returned later in the episode with the more solemn “Below My Feet,” in which Marcus displayed his full range of musical talents — singing while playing acoustic guitar, bass drum and tambourine. Both songs are off the band’s upcoming album, Babel, scheduled for release on Tuesday, September 25.

The episode — and Gordon-Levitt — were criticized for failing to sustain a high level of entertainment, but the musical guests saved the day. “The highlights of last night’s episode came despite its host — starting with Mumford & Sons,” wrote Rolling Stone. “The crowd-pleasing nü-Bluegrass group stood like pillars, side by side at the front of the stage, and intertwined their harmonies beautifully.”

The musicians also had a stake in the comedy portion of the show, dressing up as a Beatles cover band called "Hey Dude" in a sketch featuring host Gordon-Levitt and cast members Bill Hader, Jason Sudeikis and Keenan Thompson. After putting together one of the better musical performances in recent memory, Mumford & Sons will certainly be a tough act to follow — though perhaps next week's musical guest, Muse, along with host Daniel Craig, will be up to the task.
