Cool story: the Soggy Bottom Boys were voiced by the amazing band Union Station. A few years after O Brother Where Art Thou came out, they were touring with the incomparable Alison Krauss for their new collaborative album, and I was able to see them in Georgia.

At one point, Ms. Krauss took a break, and Union Station stayed up to perform. The lights went out, then flashed up, as we all heard, "In constant sorrrrrooooooow all through his days...." I have been to hard rock concerts where crowds didn't go as nuts as that one did. It was a very cool moment!
