The Clangers: Vote for Froglet

The second general election of 1974 took place on 10 October. That day a special episode of The Clangers, which saw them trying an election of their own and not much liking it, was broadcast that evening.

I do not know if it was shown after the polls closed, but in an interview Oliver Postgate said it was not shown at the usual time for children's programmes.

Vote for Froglet has long been thought lost, but the good news is you can watch  the whole thing on the British Film Institute website.
