Chappaqua is a 1966 cult film written and directed by Conrad Rooks. The film is based on Rooks experiences with drug addiction and includes cameo appearances by William S. Burroughs, Swami Satchidananda, Allen Ginsberg, Moondog, Ornette Coleman, The Fugs, and Ravi Shankar. Rooks had commissioned Coleman to compose music for the film, but his score, which has become known as the Chappaqua Suite was not used. Ravi Shankar then composed a score.
