Ain't Supposed to Die a Natural Death, the rarely seen 1971 black musical by Van Peebles, is currently getting an Off-Broadway revival as part of the Classical Theatre of Harlem's 2004-05 season. Dates are Sept. 29-Oct. 31. Natural Death premiered on Broadway on Oct. 8, 1971, and went on to a 325-performance run, first at the Barrymore Theatre, then, after a 10 month break, at the Ambassador. Van Peebles—best known as the filmmaker behind the trailblazing early '70s films "Watermelon Man" and "Sweet Sweetback's Baad Asssss Song"—authored the score and book. Gilbert Moses directed a large cast which included Bill Duke, Arthur French, Albert Hall, Garrett Morris, Carl Gordon, Beatrice Wind and Lauren James.
