The original transmission and the CBBC re-run circa February 1994 includes a scene in the cloakroom where Mr Sutcliffe interrupts Cathy Hargreaves and her friends Ruth and Gerry dancing and singing along to "Daddy Cool" by Boney M playing on a transistor radio. This scene is deleted on the official DVD release, probably because the DVD producers could not afford or obtain permission to use this song.
