Rock-a-bye, Baby, In the tree top: When the wind blows, The cradle will rock; When the Bough breaks, The cradle will fall; Down will come baby, Cradle and all. Alternate lyrics from The Real Mother Goose (1916) Rock-a-bye, baby, thy cradle is green; Father's a nobleman, mother's a queen; And Betty's a lady, and wears a gold ring; And Johnny's a drummer, and drums for the king.
