DESCRIPTION:
(Must be sung loud and raucously, with not too much attention to correctness of lyrics.)

Listen to the chorus
Of the brontosaurus
And the stegosaurus
Down by the swamp.

Along comes a dinosaur
Making such a loud roar
Thumping with his feet and going
Stomp, stomp, stomp.

Pterodactlyl flapping
Long beak clacking
Big teeth snapping
Down from a tree.

Here's a wooly mammoth
Tusks all curly
Joins the hurly burly.
Oh dear me

What a noise!
It's the boys of the
Prehistoric Animal Brigade!!!
