 Dennis departed "Coronation Street" on 12 June 1968, shortly after marrying girlfriend Jenny Sutton.Introduced as a teenage tearaway, Dennis quickly became a reformed character and for most of his time on the show, Dennis was primarily used as the show's comic relief with his story lines revolving around his interest in show business, much to the annoyance of his mother Elsie (Pat Phoenix).Dennis was later described as "immensely popular".
