'A World Is Born'--anyone remember?

When I was a kid in elementary school, it was always a joy to come in after recess and see the film projector there. (Remember the days of 16mm films in class?)

One of my favorites (which I remember seeing several times) was "A World Is Born", a Disney animated short about the beginnings of Earth, the evolution of life, and the rise and fall of the dinosaurs--all with a continous narration. There was some pretty cool music underneath, as I thought at the time, but back then my focus was on the animation and narration.

Imagine my surprise years later when I found out that the segment (sans narration) was part of Fantasia!

Does anyone else remember seeing the Rite of Spring segment as "A World Is Born"?
