One night in the 80's I went to Biddy Mulligan's bar/club in Chicago. For $5 cover charge I was in front of John Lee Hooker and his Coast to Coast Blues Band with invited guests: Willie Dixon and Chuck Berry. Today, all of them are gone and Biddy Mulligan's is closed, but my memories will stay forever.
Opening Acts For the Rolling Stones
One of the things I always admired about the band was their choices of opening acts. I speculate that early in their careers they may not have had much input, but starting around 1969 things changed. Here's a link to a website that actually lists every opening act since July 12, 1962 (Long John Baldry). I could be wrong, but I think Buddy Guy has done it the most.
