"Magician Ali Bongo, who made numerous appearances on television, has died aged 79 after suffering a stroke.
Bongo - whose real name was William Wallace - also acted as a consultant on programmes including The Paul Daniels Magic Show and Jonathan Creek."
I remember him as an assistant to David Nixon back in the black and white TV days.
