Medicine Ball Caravan is a scaled-down Woodstock-ish rock concert documentary. Director Francois Reichenbach followed a large troupe of performers known as the Caravan as they made a nationwide tour in 1970. The avowed purpose was to preach a doctrine of Peace and Love, but most people came to "groove." Among the featured performers are Alice Cooper, B.B. King and Doug Kershaw. Martin Scorcese, who'd previously been a co-supervising editor on Woodstock, both edited and functioned as associate producer of Medicine Ball Caravan.
