I've had both of them for over 15 years, personally I've seen more copies of "Fine, Fine,Fine" than "Emotion", though there is more demand for the former.
Virtually all of the incidental music was by Ron Grainer, none was commercially availble at the time (1967), the Prisoner fan club has released some on a small scale since 1977, which episode was it by the way?
