Hello. I'm seeking information about a long series of pop performances filmed at Rank House in the early 1970s and featuring most of the top acts of the day (Sweet, Stones, Gladys Knight, David Essex etc etc). These performances were shot especially for domestic and international TV sale and were directed by Steve Turner and produced by Paul Nobel. Do any of you TV music enthusiasts know anything aboput these films, such as: Who owns the copyright? Who were the production company? Where they sold? Where they appeared on British TV? Any info gratefully received.
