You're The Only World I Know

You're the only world I know 
You're the one I can't let go
You're my laughter and my tears
And, I love you all my years
You're the beating of my heart
You're my thoughts when we're apart
You're the one I can't let go
You're the only, only world I know
(chorus)
You're my nighttime and, my day
You're my one love all the way
You're the one I can't let go
You're the only, only world I know
