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

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
