In this week's episode, Tony Hatch interviews the maestro of American TV theme music, the multi-Grammy Award winning Mike Post, during the 70s and 80s you couldn't switch on the telly without hearing one of his themes, he's the man responsible for The Rockford Files, Hill Street Blues and The A-Team! Composer Murray Gold tells us how 12 years ago he was given the poisoned chalice which turned into a glorious goblet when he was given the task to update the arrangement to the original Dr Who Theme. The title "Studio 69" may not mean anything to you but we learn from Alan Hawkshaw, the King of library music, that this composition turned into "Dave Allen At Large", and the title "Chicken Man" was used as "The Grange Hill Theme", not only that but it was used for Michael Aspel's "Give Us A Clue"!

Radio 2 presenters Steve Wright, Tim Smith and Jo Whiley reveal their favourite themes and why - they are The Avengers, Banana Splits and The Prisoner but who chooses which?

This week Tony will transport you back to test you on a medley of children's theme and it's the turn of 1970s and 80s and also he asks the question why during those decades was there a fashion for espionage programmes and indeed horses, so expect some "Mission Impossible" and "Black Beauty".
