As with all missing episodes, off-air recordings of the soundtrack exist due to contemporary fan efforts. In 1992 a set was released on audiocassette, accompanied by linking narration from the Fourth Doctor, Tom Baker. However, due to problems with background music clearance the scenes set in the Tricolour in episode one had to be deleted. Subsequently, better quality copies of the soundtrack emerged and in 2003, the remastered soundtrack was re-released with the excised scenes restored (albeit with the song "Paperback Writer" changed to "Hold Tight!") and with new narration by Frazer Hines. This CD release contains bonus tracks featuring the end of "Episode 7" without narration, raw dialogue and sound effect recordings and the narrated opening to "Episode 1" from the 1968 repeat.
