The colour master videotape of this episode was wiped by the BBC in the 1970s and the BBC only held a 16mm black and white telerecording. A poor quality colour NTSC version taped on a home recorder also existed. The episode remained only in black in white until the 1990s, when the colour signal from the NTSC version and the black and white telerecording were used to create a new colour master on D3 digital tape.
