But before I disappear to the Nebraskan frontier, I want to post a link to Singing Science Records. 'Tho, sadly, the Eohippus song is out of date. "Hyracotherium Lullaby" these days. In the song it is, strangely, compared in size to a fox rather than a fox terrier.

I really like the "Ballad of Sir Isaac Newton", too.
