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."

Deep in the heart of the infinite darkness, a tiny blue marble is spinning through space. Born in the splendor of God's holy vision, and sliding away like a tear down his face.

[Sam Phillips] laughed at me. I just didn't like the way I Walk The Line sounded to me. I didn't know I sounded that way. And I didn't like it. I don't know. But he said let's give it a chance, and it was just a few days until - that's all it took to take off.

The requests started coming in from other prisoners all over the United States. And then the word got around. So I always wanted to record that, you know, to record a show because of the reaction I got. It was far and above anything I had ever had in my life, the complete explosion of noise and reaction that they gave me with every song. So then I came back the next year and played the prison again, the New Year's Day show, came back again a third year and did the show.
