Santa Claus Is Comin' T Town. 1970.
A mailman tells the story of Santa Claus to some children.
I totally forgot that this even existed, saw it when I was primary school maybe twice, three times at the most. Fred Astaire provides the voice of the mailman and brings along his singing talents as well. Mickey Rooney provides the voice on Kris Kringle and Paul Frees as the greedy Burgermeister Meisterburger. This is one of those jolly happy kids/family animation film that lasts under a hour but entertaining.
