Two more obscure questions:
1. From reading newspaper reports of the 1955 Hughie Green "Opportunity Knocks" court case, I know that the short-lived "Spot the Winner" from 1949 was a revival of the Carroll Levis show "in a different form". How did it differ?
2. A very long shot, but I may as well ask: I know the 1937 Radio Luxembourg series had winners, and I think even had a postal vote. Did the 1936-7 BBC Regional Programme series have winners, and especially, did the one-off TV broadcast from Alexandra Palace in 1936 produce a winner or was it just a non-competitive showcase?
