Worth's first television appearance was a five-minute standup on "Henry Hall's Guest Night" in 1955. He became well known to the public and even appeared at the London Palladium, after which he took the show to Manchester, the main place for variety in those days, for 8 weeks. In 1960, the television programme "The Trouble With Harry" was broadcast. John Ammonds and Worth wrote the pilot script in three to four weeks. A series of six programmes was commissioned, and was written by Vince Powell, Ronnie Taylor and Frank Roscoe.
