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.
