Unusually, for a small British sitcom, it's theme tune was specially composed by the prolific American musician, composer, arranger and producer, Mike Post, who has long been considered the most successful composer in television history. This came about as Mike Bubbins was writing the show while he interviewed the composer for his weekly '70s-themed show on BBC Radio Wales in the summer of 2021. They remained in contact and Post told Bubbins to get in touch should the show be commissioned.
