the mcghees.

As sure as night is dark and day is light 

I keep you on my mind both day and night 

And happiness I've known proves that it's right 

Because you're mine, I walk the line 

You've got a way to keep me on your side 

You give me cause for love that I can't hide 

For you I know I'd even try to turn the tide 

Because you're mine, I walk the line

-Johnny Cash
