Hello Billiam, Yes, Buddy Guy outta Chicago. I was lucky to find a dvd called ,"Super Show", that was filmed in London back in 1969. ( I just missed meeting him at Chess & Checker Studios (Chicago) back in 1970.) The DVD has Buddy along with Eric Clapton, Stephen Stills,and Buddy Miles.It was produced by Eagle-Rock Entertainment.  It also features 2 Jazz Quartets.                       I found it in a sale bin.  Buddy sure is young in it , along with Clapton,Bruce, and Stills.  Peace.
