Serving in his capacity as honorary chairman, Capp made public appearances on its behalf for years, contributed free artwork for its annual fund-raising appeals, and entertained crippled and paraplegic children in children's hospitals with inspirational pep talks, humorous stories and sketches.

Two of the constables who observe Andy's drunken behavior are named Alan and Trevor. Reg Smythe died on 13 June 1998 but the original strip has continued.
