Dinosaur Song from my childhood...help!!

[ferbil]

I know all of the lyrics but not who sings it...it used to be in a book with a bunch of other songs. here goes:
When walking to the zoo do you look behind you to see if you're all alone?
when you hear the stomp of feet behind you on the street do you shake when you see who's there?
It's a big dinosaur, a friendly dinosaur, with points on his back to his tail, ROAR...his roar turns pouty people pale.

Please help:)
