A while ago (and maybe still today -- it's been a while since I've seen a proper Wilco show), Wilco played a great tune prior to coming on stage. I believe it is called "The Man," or "I Saw the Man," or something like that. At one point I think I had zeroed in on the actual name and the song's performer, but I was never sure and I've lost track of it at any rate. I'm sure I saw them use this tune at the Auditorium (Chicago), possibly more than once. Can anyone help me ID the song / artist? Thanks!
