I attended the Festival four times in the years 1979-1989, and there was always a strong jazz presence, with at least one stage devoted exclusively to jazz, both traditional and modern. Aside from the many fine local jazz artists who played, I saw Sonny Stitt, Art Blakey, Sam Rivers, to name three. I remember a group that was under George Wein's leadership that included Warren Vache, Scott Hamilton, and Harold Ashby (who blew everybody away).
