And if that Mocking bird won't sing
Mamma's gonna buy you a diamond ring

And if that diamond ring turns brass
Mamma's gonna buy you a looking glass 

And if that Looking Glass gets broke
Mamma's gonna buy you a billy goat

And if that Billy Goat won't pull
Mamma's gonna buy you a cart and bull

And if that Cart and Bull turn over
Mamma's gonna buy you a dog named Rover

And if that Dog Named Rover won't bark
Mamma's gonna buy you a horse and cart

And if that Horse and Cart fall down
You will still be sweetest baby in the town
