I walk the line...

I keep a close watch on this heart of mine
I keep my eyes wide open all the time.
I keep the ends out for the tie that binds
Because you're mine,
I walk the line

I find it very, very easy to be true
I find myself alone when each day is through
Yes, I'll admit I'm a fool for you
Because you're mine,
I walk the line

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
