It's a subtle point, but, in fact, the owner of the tapes is the one who decides how the tapes are used. If they are used for commercial purposes, there are circumstances under which performers and others may have rights to compensation. It is also possible that, due to the circumstances of recording, the time and location of the original recording, and other circumstances, that none of the other rights are enforceable. The claimant has to be able to prove that their claims are valid.

Beyond that, not all reproduction and distribution is for profit--so there is plenty to argue about, and plenty for a judge to decide on, if anyone decides to make an issue of it.

Even beyond that, there is no money to be made here. If anything, it's going to take a big investment in time and money to make this project happen.

Artful Codger, and those who take this opportunity to make forceful statements about punitive damages and such things, unwittingly discourage the few people who have these wonderful documents from sharing them. Why risk expensive legal hassles? Better just to leave the stuff to rot.
