The first half of my reconstruction of this missing episode, made using stills, video clips and the surviving soundtrack.
Well, I say "my"... Due to the lack of John Cura tele-snaps, many of the images I've used are composites and CGI from Loose Cannon's excellent reconstruction. However, I have made some modifications, including a few new images.
I have the soundtrack in two forms, narrated (by Peter Purves) and non-narrated. I have combined the two so that the narration is present only where I deem it necessary.
The picture quality varies, so I wouldn't recommend watching this full screen!
The complete soundtrack is available on CD from BBC Audio. Support the BBC releases.
