The Fiasco band played with Wesley for a while, but IMHO that stuff was garbage. I saw him last spring in Rochester, NY, and at the end of each song, he said “Rock over London! Rock on Rochester!” which elicited much verbal approval. More importantly, the concert was 5 dollars, and Wes began the show in curse-laden a cappella fashion for about 20 minutes that seemed to rile the crowd into a frenzy. I got a picture with Wesley at the concert with a buddy, but unfortunately Wes was really involved with the drawing he was creating and so he wasn’t looking at the camera.
If you’re into piracy, download his appearance from Howard Stern a couple years back (you can find it by searching for Wesley Willis in your favorite P2P). The interview (sort-of) answers some of the questions raised so far, but more importantly he talks in the same manner in which he sings.
“Batman whooped my ass and knocked me to the floor,
Then I got up and knocked him to the floor,
He was bein’ such a jagoff.”
