Lyrics:

(Johnny Cash)

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 ties that bind
Because you're mine I walk the line.

I find it very, very easy to be true
I find myself by myself when each day is through
I'll admit that I'm a fool for you
Because you're mine I walk the line.

--- Instrumental ---

I'll admit that I'm a fool for you
Because you're mine, let me, I walk in the line.

--- Instrumental ---

I keep a close watch on this heart of mine
I keep my eyes wide open all the time...
