Someone on here is bound to know it, but in the meantime, maybe a little more info? Do you remember what channel it was on and/or what date & time? That way we could figure out the name of the movie and it would probably make it a lot easier to then figure out the tune. Did you recognise any of the actors? What era was it set in?This is the kind of quest Mudcatters love to take on, so hang in there and get ready for an answer!
All the best,
