Saw Hank a few times during his stay in Chicago. Once in a church with his "working band" of Muhal Richard Abrams, Frank Gordon, Rufus Reid and Wilbur Campbell. Once in an all-star deal put on by Joe Segal - Hank, Jug, Hank Crawford, (maybe) Von Freeman and a good rhythm section. Don't think it was the concert pictured, but maybe. Hank was always friendly and "cool" when I encountered him.
