All I am saying is that "The Zoo Song" is A LOT more well known than " The Last Thing."
As to the artistic merits of the two songs, well that's a different question.

The "Zoo Song" is terrific. A beautifully written song that really engages children.
Today, all over the world, children will be swinging an arm in lieu of a trunk, and pretending to scratch themselves like a monkey.

"The Last Thing.." is one of the great "lost love" songs.

In closing, it's clear to me, that a number of mudcat posters live in a "folk bubble" and should get out into "the real world" a bit more.
