Upton auditioned at Hill's flat in the Kensington area of London in 1976, and was hired shortly after. Hill said of her at the time, "Sue is really funny. Finding pretty girls who are talented and funny is not easy. And not all girl dancers are pretty. Some of them look like me in drag. Sue is pretty and she is funny." She made her Benny Hill Show debut in the episode originally telecast on 26 January 1977.
