That's a blast from the past! I remember the name Humphrey Lestoq, but can't remember any details of the programme. I would have been about 13. We had our first TV in 1953 for the coronation as did so many people.
I remember Muffin the Mule more clearly, that was on Sunday teatime I think. Also Andy Pandy, I could go on......
I remember it and always thought it was Peter Butterworth , hosting it and can remember him trying to boil a kettle holding it over a candle ? Or maybe not.
