The outbreak of the Second World War saw him enlist in the Royal Air Force, where he became a navigator stationed at RAF North Killingholme, Lincolnshire.

He appeared as several characters in Milligan and John Antrobus' stage play The Bed-Sitting Room, which opened at the Mermaid Theatre on 31 January 1963.

In 1973, he appeared as Bill Thompson, the referee at a regimental boxing tournament in Adolf Hitler: My Part in His Downfall.

Producer Dennis Kirkland persuaded Hill to rescind the decision, saying Todd brought much to the show and his drinking rarely affected his work.

He died at home (six months after Benny Hill did) at the age of 70 in the village of Burwash, Sussex from myocardial hypertrophy.
