I think I've told this before in here. I was at this Dylan Merriillville, IN (Gary suburb, north of Purdue) show at the Holiday Star Theatre in 1981. Right before the last song of the night, he says "I've got a friend I want to bring out." We had no idea who it was. Maybe Robbie Robertson? Instead this guy comes out in a wheelchair. They adjust the mic for him and he sings a song I didn't recognize, all the while Dylan's all over the place playing sax. One of the wildest things I've ever seen at a concert.
