In one of his recent columns in Yours, a fortnightly magazine for women over the age of 50, Roy says Belfast was “the home of someone who makes me laugh”.
The 79-year-old adds: “If you think he’s just a loveable, welly-wearing, ‘dacent Irish boy’, be amazed.
“He does the lot. He sings and writes songs, juggles, does impressions, dances (inspired by Billy Dainty) and is always on the ball with topical stuff.”
Roy also describes Jimmy as “the perfect pantomime performer”.
As well as being a comedian, Roy is also an actor – he appeared as undertaker Archie Shuttleworth in Coronation Street – a radio host, author and authority on the history of music hall entertainment.
