Fun fake fact: Jimmy Kimmel and Mumford & Sons were in a boy band together back in the late 1990s.
In honor of the chart-topping rock band performing on “Jimmy Kimmel Live” on Wednesday, the late-night host created a mockumentary about their former group, Mumtown, responsible for hit songs you’ve never heard, like “Girl, I’m Saying Girl, Girl” and “O.M.G.U.H.O.T.”
Kimmel’s nickname was “Mum,” and Mumford & Sons members Marcus Mumford, Ben Lovett, Winston Marshall and Ted Dwane all make appearances to explain how the comedian got it: He never sang. Instead, Kimmel opted to be the band’s chief lyricist.
But when the band hated the songs Mum produced, tensions grew, and Mum eventually left the band to start his solo career.
Watch the video above, then watch the band play one of their actual songs, “The Wolf,” below.
