Another 4-gotten classic moment

Originally, Big Bird sang "I Just Adore Four" as part of a tribute show-within-a-show (Episode 734, from the mid-1970s). I distinctly remember watching this one as a girl; the Count's getting carried away with multilingual counting still sticks in my mind. If anyone out there got hold of a tape from some PBS station, I'd love to see the whole episode and refresh my memory...
