You can sing this song in two parts, with one group repeating “monkey, monkey” while the other sings the verse.
We went to the animal fair,
The birds and the beasts were there.
The big baboon, by the light of the moon, was combing his golden hair.
The monkey fell out of his bunk,
Thump,
Slid down the elephant’s trunk.
Wheeeee.
The elephant sneezed and fell on its knees,
But what became of the monkey, monkey, monkey, monkey.
