First appearance of the character of Blanche Hunt (Deirdre's mother). In this episode and the next, the part was played by actress Patricia Cutts. The intention was that the part (and the actress) would become regulars on the programme but Ms. Cutts tragically committed suicide on 6th September 1974. When the character returned on 30th September 1974, she was played by actress Maggie Jones who was a choice for the part at the original auditions and was only rejected because it was felt that she would be too familiar to viewers from her recent starring role in the Granada series Sam which was written by John Finch.
First appearance of Vera Duckworth and last until 19th July 1976.
