以下是英文兒歌《rock a baby》的詞曲：
Rock a baby, rock a baby,
rock him in the cradle,
Rock him till he's ready
to go to bed.
Shake a feather, shake a feather,
shake it up in the bed.
Shake it till he drifts off
and dreams of lullabies.
Cradle will rock, cradle will rock,
rock him all night long.
Bells will ring, bells will ring,
when the sun comes shining through.
(Chorus)
Lullaby and goodnight, my dear little one,
In slumber sweet, your worries all unwind.
Sleep well till the sunrise, baby my own,
Lullaby and goodnight.
Every lullaby's a magical spell,
Some play sweet music and some whisper in a shell.
But every mother's child is special and so are you,
So let's sing our lullaby and goodnight to you.
(Chorus)
