If you're asking about a soundtrack then here's a snippet from someone's post on the Radio 4's forum :
"The song was called Silent Running (on dangerous ground) from their first album. Used as part of the soundtrack to the 1986 film strangely entitled 'On Dangerous Ground'."
However, the only film I am able to find on IMDb, Wikipedia and Google with the title of 'On Dangerous Ground' is the 1952 thriller. But it is actually on a film called 'On Dangerous Ground' as it's mentioned on the Mike and the Mechanics fan site "houseofmanyrooms.com"
