Pete,
The comment about the version you seek being (possibly) an Australian version alerted me to the possibility that you might be seeking the version that Pageant did in the 70s. We put out a cassette but I'm not sure if any survive and I don't (yet) have the technical expertise to send you an mp3 file. I have sent your request to Tony Suttor, who I'm sure can help you if the dry season hasn't lured him out of reach of email.

Cheers, Rowan
