In the 1990s, before the CD releases began, several Doctor Who stories were released on audio cassette. In addition to those shown here, there were a number of others which are missing from my collection: "The Massacre of St. Bartholomew's Eve" with William Hartnell, "The Tomb of the Cybermen" narrated by Jon Pertwee, the release of which was delayed by the discovery of the full film print, and "The Paradise of Death", the first of the two Barry Letts UNIT-style revivals.
