Many years ago when I was a child the early movie networks like HBO and The Movie Channel used to fill their interstitial between movies with short films, usually cartoons. I distinctly remember even after all these years seeing a cartoon That begins with an astronaut leaving a glass bottle of soda with a drop left in it. Then Ravels Bolero begins and the cartoon shows the unfolding of a whole evolution based on that drop. I particularly remember the animals marching to the music and a line of marching dinosaurs. Does anyone else remember this cartoon, it’s name, and where I might find a copy? I seemed to recall there was some kind of Russian connection but that part is hazy so I may be mistaken.
Any replies will be appreciated,
