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's 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. 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.
