Thanks for the info. I was hoping that you had something truly unique and even historical. Hmm, on Beta? It sounded plausible. I've become very interested in this film, to the point that it has inspired me to learn a bit of Esperanto. Normally a movie won't do that!

I'm genuinely curious as to exactly what your parents recorded. Was it from an odd appearance on TV long before the rediscovery of Incubus? If so, you have a real artifact of interest.
