The Cuckoo Waltz is a British television sitcom produced by Granada Television for the ITV network between 27 October 1975 and 7 August 1980. It was written by Geoffrey Lancashire, and produced and directed by Bill Gilmour.
The series, which was set in 1970s and early 1980s Manchester, dealt with the comic complications that ensue when impoverished newly-weds Chris and Fliss Hawthorne (David Roper and Diane Keen) take in lodger Gavin Rumsey (Lewis Collins) to ease their financial problems. Collins left after three series and was replaced by Ian Saynor as Adrian Lockett in the fourth series.
The series was re-screened by now defunct satellite TV channel Granada Plus in the late 1990s and early to mid-2000s. Since 2024, it has been shown by Rewind TV, along with other Granada sitcoms such as Surgical Spirit and Watching.
All four series of The Cuckoo Waltz have been released on DVD in May 2009 and August 2011, and a box set with the complete series to follow.
