Canadian Railroad Trilogy is an extremely fine piece of songwriting.

I wore black because I liked it. I still do, and wearing it still means something to me. It's still my symbol of rebellion -- against a stagnant status quo, against our hypocritical houses of God, against people whose minds are closed to others' ideas.

It's like a novelist writing far out things. If it makes a point and makes sense, then people like to read that. But if it's off in left field and goes over the edge, you lose it. The same with musical talent, I think.

I learn from my mistakes. It’s a very painful way to learn, but without pain, the old saying is, there’s no gain.

I started to write the song. And I was in Gladewater, Texas, one night with Carl Perkins and I said, I've got a good idea for a song. And I sang him the first verse that I had written, and I said it's called "Because You're Mine." And he said, "I Walk The Line" is a better title, so I changed it to "I Walk The Line."

We went down [Folsom Prison] and there's a rodeo at all these shows that the prisoners have there. And in between the rodeo things, they asked me to set up and do two or three songs. So that was what I did. I did "Folsom Prison Blues," which they thought was their song - you know? - and "I Walk The Line," "Hey Porter," "Cry, Cry, Cry." And then the word got around on the grapevine that Johnny Cash is all right and that you ought to see him.

I knew I wanted to sing when I was a very small boy. When I was probably 4 years old. My mother played a guitar and I would sit with her and she would sing and I learned to sing along with her.
