Hush little baby
Don't you cry
Papa's gonna sing you a lullaby
[ Lyrics from: http://www.lyricsfreak.com/l/led+zeppelin/hush+little+baby_20082178.html ]
Hush little baby
Don't say a word
Papa's gonna bring you baby a mocking bird

And if that mocking bird won't sing well
Papa's gonna buy you a diamond ring

If that ring don't shine
It would break this heart of mine
