I want you to promise me
Promise me that you'll be faithful
Promise me you'll never be ungrateful
Say the words that you will never be untrue
And I'll sing a lullabye to you.

Promise me that you will treat me kind
Say the words that you'll always be mine
Promise me that you will never be untrue, no
And I'll sing a lullabye to you

Sing a lullabye of loving
Sing a lullabye when you are blue
Sing a lullabye of happiness
Yes, I'll sing a lullabye to you.
