The song was written by Trent Reznor of Nine Inch Nails. Johnny covered it. Trent at first didn’t like the idea of Johnny doing it but was sent the video while in the studio with Zach De La Rocha of Rage Against the Machine, they watched it together and it hit hard. He later said the song was Johnny’s now. It was partially filmed at his Museum The House of Cash which had been closed for some years before the video and partially filmed at his home. The woman on the stairs is his wife, June Carter Cash, also a singer. It was an intense love story between them. This video hits harder knowing June died three months after filming, and Johnny died seven months after. This was his last hit. On the Johnny Cash vs Elvis thing, they were both important but very different. Johnny performed world wide and is now in the Rock and Roll, Country, and Gospel Halls of fame. Elvis is all those halls of fame plus a bunch more even though he never played outside the U.S. Both had their problems with alcohol and drugs. I think Elvis’s career was bigger though not as long since he died sooner, Johnny was more of a rebel. Both did TV, Elvis did movies. I personally like Cash better probably because he’s rougher around the edges, though my parents loved his gospel album.
