In the mid 1960s, Johnny Cash, who was already an established star, signed to Columbia Records. In an effort to make as much money out of their new star, Columbia released I Walk the Line, an album filled with rerecorded versions of his biggest hits released through his old label. Cash grab though it was, there’s no denying that these are great songs are great. Big River, Folsom Prison Blues, Hey Porter, I Walk the Line…half of these songs were on the career spanning “Legend of Johnny Cash” released after his death.
