Johnny Cash has been awarded with a posthumous title for the "greatest Love letter of all time," because, you k**w, we live in an era where such things need to be ranked. Everyone k**ws a Love song or two by the Man ink Black ("I Walk The Line" being one of the more confusing) and everybody k**ws about his marriage to June Carter Cash, thanks to the film with almost the exact title. Even the most cynical among us (aka your correspondent) will find a bit of relief in the form of Cash's letter to his wife, which he wrote her during 1964 for her 65th birthday.
