Yes- the New Zealand show was filmed and aired on TV. Since nobody in New Zealand had a VCR in 1978 the TV studio had the only copy of the show. A fan happened to visit the TV station about 15 years ago and the tape was still there molding away- but no copy has ever surfaced to my knowledge
Hmmm.. do you know where the TV station is situated Ian? I may have to pay a visit to New Zealand
