Career: After leaving the Army, Williams landed work as a professional actor in repertory companies. On the strength of his performance in a production of Saint Joan, he was hired by a radio producer to do voice characterisations in radio comedy Hancock's Half Hour. His popularity on radio soared in the 1950s and 1960s when he starred with Kenneth Horne in Beyond Our Ken and Round the Horne. Williams also appeared in a number of revues on the stage in the West End, but he was best remembered for his comedy roles on the big screen in the Carry On films. He appeared in 25 of the Carry On films between 1958 and 1978. When the film work dried up, he became a regular on TV talk shows. He died on April 15, 1988 at the age of 62.

Career: Two major film roles in 1962 - Death Trap and Sparrows Can't Sing - resulted in greater recognition, but it wasn't until stage show Fings Ain't What They Used to Be that Windsor found true fame. Her career really took off after her appearance in the comedy film Carry On Spying. Stereotyped as a glamorous dolly bird, she was seen as the ultimate Carry On girl and appeared in nine of the classic movies. In recent years, she has appeared in the long-running soap EastEnders, playing Peggy Mitchell and becoming a genuine soap icon. She left Walford in 2010, and since then has done panto and regularly stood in for Elaine Paige when she's been unavailable to host her Radio 2 show.
