I know it was from the deleted segment of Mary Poppins where they traveled to all four corners of the globe or something, and the song from the East, titled "Land of Sand" was reused in "The Jungle Book" as Kaa's song, "Trust in Me".
If you haven't heard "Chimpanzoo", you're not missung too much, IMO. It's not as good as anything in the chalk portrait scene which replaced it.
