I wonder if that is the show that I was thinking of, because it was at Great Woods, and I remember he sat in a chair for most of the show. I guess time really does fly!
Probably 1997—I looked up Blues Bros. 2000 under Wiki and it said it came out in Feb of 1998, and the BB show was maybe in the summer or fall of 97, then.
BB: “When they made the Blues Brothers movie, they didn’t put me in it...” (Crowd laughs, some boos). “Well they just made another one...I’m in THIS one!” (Crowd cheers.)
