Hi,
The release is from Spain and recorded inside an empty Movie Theater in 1983 (sadly it has no audience reactions in it) I can send you a link with a compressed version of the file. For the original one I would like to get in touch with the people you mentioned (if that’s possible) I’m a collector of old theater-recorded versions and I’m happy to put my find to the other versions that have been found.
here are also some shots for the titles:
