He made many appearances on BBC Television's variety show, The Good Old Days in the 1970s and 80s. When Richard Wilson turned down the part of Victor Meldrew in the BBC sitcom One Foot In The Grave, Writer David Renwick considered Dawson for the role, but Wilson changed his mind before it was offered. His final TV appearance was on the LWT series Surprise, Surprise hosted by Cilla Black, in which he sang a comic rendition of "I Got You Babe" with a woman from the audience who wanted to sing with him. The episode was aired shortly after his death.
