Ah now I understand the connection to 4FTS. BTW for fans of the CBC recording, if you go to the link given by A330, and access the 38:25 version listed from whodannywho, there is an initial 5-6 minute interview with Frederick Forsyth regarding the story, and then he begins a narration, fading into Alan Maitland. I'm not sure if the interview is available separately.
I used to live near Worksop!
