After three attempts with moderate chart ratings, it became Cash's first number one hit on the Billboard charts . It reached number 17 on the US pop charts . It remained on the record charts for over 43 weeks, and sold over 2 million copies . It has also been used on many LP's released from Sun Records, such as With His Hot and Blue Guitar, Sings the Songs That Made Him Famous, and Sings Hank Williams . It was the title song for a 1970 film starring Gregory Peck . </P> <P> The unique chord progression for the song was inspired by backwards playback of guitar runs on Cash's tape recorder while he was in the Air Force stationed in Germany . Later in a telephone interview, Cash stated, "I wrote the song backstage one night in 1956 in Gladewater, Texas . I was newly married at the time, and I suppose I was laying out my pledge of devotion ." After the writing of the song Cash had a discussion with fellow performer (Carl Perkins) who encouraged him to adopt "I Walk the Line" as the song title . Cash originally intended the song as a slow ballad, but producer Sam Phillips preferred a faster arrangement, which Cash grew to like as the uptempo recording met with success . </P> <P> Once while performing the song on his TV show, Cash told the audience, with a smile, "People ask me why I always hum whenever I sing this song . It's to get my pitch ." The humming was necessary since the song required Cash to change keys several times while singing it . </P>
