Promise me that you'll be faithful
Promise me you'll never be ungrateful
Say the words that you will never be [bad word] 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 [bad word]  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
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.
