Why are there no “Years” tapes for Peter Davison or Sylvester McCoy?
The “Years” tapes were all produced by former Doctor Who producer, the late John Nathan-Turner. He made tapes for the first four Doctors and then intended to move along to the last three. Due to scheduling quirks, the links for Colin Baker’s tape were shot in advance of Davison’s and McCoy’s, and then before those other two could be made, John Nathan-Turner left (or was asked to leave) BBC Video, and the Years projects came to an end. With the Colin Baker tape already in the can, it made little sense to hold it back, so it was released. There will probably not be any further Years tapes of this format produced.
