Here is the fourth episode of Time Out of Mind. It features Anne McCaffrey. The fifth and final episode, shot at the 1979 Worldcon, has already been uploaded to YouTube by someone else and can be found here.
Aside from the small amount of copyright material in the John Brunner episode, everything appears to have gone up OK. Fingers crossed it will stay there. Of course I hope that the BBC still have the original files somewhere, and will one day produce decent quality versions of the series for sale, but for now I hope you have enjoyed what we have got. Thanks again to Arnold Aiken for sending me the recordings.
