Close Your Clothes book - overalls clasps page

The facing page poem reads:

Old MacDonald had a farm (E-I-E-I-O!)
And on his farm he worked quite hard (E-I-E-I-O!)
He herded his sheep, and he milked his cows,
Tended chickens, walked his dog,
Every night went for a jog!

Old MacDonald one fine day (E-I-E-I-O!)
Didn’t buckle his overalls all the way (E-I-E-I-O!)
How his animals laughed when his pants fell down
Cows said MOO-ha! Pigs said OINK-ha!
And his doggie barked a WOOF-WOOF-ha-ha!
