The Town Hall story is a mess, and Bernard has discussed it with me in a fair amount of detail. I understand that ESP only had one of the tapes, a copy from the master that they had repaired due to some audio problems. This became ESP-1006. Ornette later took the masters to BN but they were unreleased, and I'm not sure who has them now.
The original Chappaqua Suite was issued both as a French and UK CBS title, with a reissue in the '70s in Japan on Sony, followed by the 1996 Columbia France reissue.
The Ravi Shankar soundtrack was issued in the States, and I assume for foregin markets as well. I wonder if contractual issues were the reason the Ornette didn't come out here?
