Boston Globe Jazz Festival
"The first time we played with Rahsaan Roland Kirk was at the 1968 Boston Globe Jazz Festival. After his performance, when introduced to him backstage, I said I really liked what he was doing, and said that if he felt like joining us onstage during our set, he was more than welcome. In spite of his blindness, I believed we could accommodate whatever he wanted to do. We began our set, wending our atonal way toward a medley of 1950s-style honking saxophone numbers. During this fairly complicated, choreographed routine, Rahsaan, assisted by his helper (can't remember his name), decided to join in." - Frank Zappa in The Real Frank Zappa Book, though he remembered the year incorrectly.
