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 that 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
