Lyric excerpt: I Walk the Line by 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 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
