"Man of Constant Sorrows" by the Soggy Bottom Boys
It's one of my ringtones.

I thought there's no such thing as the Soggy Bottom Boys.
That was a movie. The voices were dubbed. One of the guys from Union Station, and I'm not sure who else. George Clooney didn't really sing it.
Biography by Zac Johnson
The fictional Soggy Bottom Boys are the on-screen personas of George Clooney's rootsy band in the Coen Brothers' 2000 film O Brother, Where Art Thou? The lead vocals and guitar work were actually provided by Union Station member Dan Tyminski, with backing vocals from longtime folk stalwarts Harley Allen and Pat Enright.
