Haven't yet read either the Shipton or the autobiography, but there's a story about Dizzy & southern Indiana that I hope to one day verify (or not). In the 1950s French Lick, IN (yes, birthplace of Larry Bird) hosted a pretty happening jazz festival, about as hip as this particular neck of Hoosierville ever got. The French Lick Hotel had a swimming pool that was, uh, shall we say, not open to many members of the jazz-playing persuasion. Gillespie allegedly came down from his room in royal regalia, posing as an African monarch, and singlehandedly "integrated" the pool by leaping into it fully-clothed. A great story, but one that certainly bears some form of validation.
