Hush my li'l baby, don't say a word
Mamma's gonna buy you a mocking bird
And if that mocking bird don't sing
Mamma's gonna buy you a diamond ring

And if that diamond ring turned brass
Mummy's gonna buy you a little 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, she'll buy you a cart and a bull
[ Lyrics from: http://www.lyricsfreak.com/j/jim+brickman/hush+lil+baby+with+carly+simon_20837986.html ]
Hush li'l baby, hush li'l baby
Hush li'l baby, don't you cry

And what if that cart and bull turns over?
Then mamma's gonna buy you, she'll buy you a doggie named Rover
And if that doggie named Rover don't bark
Mamma's gonna buy you a horse, a horse and a cart

And if that horse and that cart fall down
You'll still be the sweetest little baby in town

Hush li'l baby, hush li'l baby
Hush li'l baby, don't you cry
