Mumford and Sons are known for their folk, bluegrass, and, most recently, electric sound. But on Wednesday’s Jimmy Kimmel Live, the group revealed that they were once a popular boyband called Mumtown — Jimmy Kimmel was Mum, the band’s chief lyricist.

“We called him Mum because he wasn’t allowed to sing,” Marcus Mumford said of Kimmel.

With songs like “Girl, I’m Saying Girl, Girl” and “O.M.G.U.H.O.T.” Mumtown peaked in the late ’90s. But tensions between Mum and the rest of the group grew too difficult to overcome. Which is fine, because this is basically all an excuse to show Mumford & Sons’ origin story and ends with the discovery of a banjo. Mum would be okay too.
