I had a song called "Folsom Prison Blues" that was a hit just before "I Walk The Line." And the people in Texas heard about it at the state prison and got to writing me letters asking me to come down there. So I responded and then the warden called me and asked if I would come down and do a show for the prisoners in Texas.

Sam Phillips asked me to go write a love song, or maybe a bitter weeper. So I wrote a song called, "Cry Cry Cry," went back in and recorded that for the other side of the record.

Gospel music was the thing that inspired me as a child growing up on a cotton farm, where work was drudgery and it was so hard that when I was in the field I sang all the time. Usually gospel songs because they lifted me up above that black dirt.

Every week, Dennis Day sang an old Irish folk song. And next day in the fields, I'd be singing that song if I was working in the fields.

[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.

Five or six songs leaked from the original version of 'Encore.' So I had to go in and make new songs to replace them.
