I Walk The Line lyrics

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 because you're mine I walk the line
