A little bit weird, and creepy - which the British do very well !! I have remembered it, all these years, so it must have impressed me. The actual show is just not available anywhere - Somewhere along the way, I guess it was taped over, to make way for something else. The BBC was diabolical for trying to save money, by taping over stuff!! Anybody else remember?
