EP SUN 113 (US, 1958)

JOHNNY CASH: "I WALK THE LINE"

This EP was released just as Johnny Cash was leaving Sun Records for Columbia Records and some of these tracks were previously released on Sun as early as 1956. In 1957, Johnny Cash became the first Sun Records artist to release a full length LP ("Johnny Cash with His Hot and Blue Guitar") which included all four of these tracks.
