You Light up My Life from Debby Boone.

So many nights,
I'd sit by my window,
Waiting for someone to sing me his song.
So many dreams, I kept deep inside me, Alone in the dark, but now you've come along.

And you light up my life,
You give me hope, to carry on.
You light up my days
And fill my nights with song.

Rollin' at sea,
Adrift on the waters
Could it be finally, I'm turning for home
Finally a chance to say, "Hey, I Love You"
Never again to be all alone.

And you light up my life,
You give me hope, to carry on.
You light up my days
And fill my nights with song.
You, You light up my life
You give me hope to carry on
You light up my days
And fill my nights with song.

It can't be wrong when it feels so right
'Cause you, you light up my life.
