Rock-A-Bye Baby Traditional (English Lullaby)

儿歌名称：Rock-A-Bye Baby Traditional (English Lullaby)
歌词：
Rock-a-bye, baby, on the treetop,
when the wind blows,
the cradle will rock,
when the bough breaks, the cradle will fall,
and down will come baby, cradle and all.
Rock-a-bye, baby, gently you swing,
over the cradle, mother will sing,
sweet is the lullaby o’er your nest that
tenderly sings my baby to rest.
