This is one of those 1985 PBS Great Performances shows which are unobtainium on commercially available medium ... a fate with many public television broadcasts. I picked this up over the airwaves from the local PBS station in Dallas, Texas, on my first $200 off-brand mono VCR via a pair of Radio Shack rabbit ears recorded at SLP ... so not the best capture. But I still enjoy watching this version over all others, especially the awful 2002 Miramax version. British TV fans may recognize the actress playing Gwendolyn as musician Nick Drake's brother and one of the purple-wigged Moonbase controllers from the 1970 series UFO. Quite a different period performance here. There is an awful transfer of this performance currently on YouTube broken into two parts. I'll continue to watch my own VHS copy till it finally self-destructs. I've read on the British Film Institute that this performance was recorded live in 1982.
