After appearing for several more episodes in April and May 1975, Alec Gilroy was made a permanent character on the Street in June 1986 when he became manager of the Graffiti Club, and he was soon married off to Bet Lynch in what was to become a popular partnership with viewers behind the Rovers bar.
Roy left the programme in September 1992, but returned briefly in July and August 1995. In the same year he appeared in Coronation Street - The Feature Length Special, and returned to the Street for one more stint as Alec from April 1996 to December 1998. Away from the cobbles, he is well-remembered for his 1970s comedy partnership with Les Dawson. He has also appeared in episodes of George & Mildred, Bergerac, Cadfael, Last of the Summer Wine and Holby City.
Roy was awarded the MBE in 2006 for his charity work.
