FiL is one of my compadres in Iddiocy and he'll be playing some music on his Tuesday afternoon show in dedication to Patrick McGoohan. One of these songs is "I helped Patrick McGoohan Escape" by the Times.
FiL sent along a link to their 1983 video for the song which was filmed on the Portmeirion site in Wales. It's full of 'Prisoner' imagery - the ID buttons, human chess games, particular location shots, KAR120C, a penny-farthing bicycle, and even Rover makes an appearance!
You can see it here.
