The play is based around the two characters created by the comedian Les Dawson and comic actor Roy Barraclough.
Bud (1963) was a six-episode serial starring the music-hall comedian Bud Flanagan; Castle Haven (1969) was a serial for ITV about the residents of two converted Victorian houses in a seaside town in Yorkshire, featuring Roy Barraclough, Kathy Staff and Jill Summers.
The show also starred Roy Barraclough from series Four - who would go on to become Dawson's most recognisable sidekick.
In 2013, Nallon played Ada/Roy in Cissie and Ada: An Hysterical Rectomy, a stage show based upon the characters played by Les Dawson and Roy Barraclough.
