The Two Ronnies Sketch. Please help.

A friend is describing a sketch to me. Can you tell me what the title of it is please?
It involves the boys as two Magicians who are involved with diamond thieves. They get them on stage to unmask them. They confuse them with a quick routine and remarks such as "Is this your wallet?" and to the femme fatale "Is this your knicker elastic madam?"

Help please.

Kind Regards
Mike

Sounds very much like a sketch called 'Caribbean Nights', which featured on series 11 of The Two Ronnies. Was recently shown again on Gold. Great series!

Great. Many Thanks.

Mike
