Johnny Cash's Grammy-winning 1996 album Unchained was actually a collaborative effort with Tom Petty and the Heartbreakers (and a few other guests) functioning as his backup band, one with the spirit, but a fuller sound, than the Tennessee Three. L-R above: Petty, Cash, Rick Rubin, Marty Stuart
In some circles, there's a bit of confusion about the origins and evolution of the song "I've Been Everywhere," in part because so many heard Johnny Cash sing it on his American Recordings album Unchained, where he was backed by Tom Petty & The Heartbreakers. As sometimes happens, it kind of eclipsed the original 1962 American hit by Canadian-born Grand Ole Opry legend Hank Snow, whose single became a # 1 country hit that year. Though many others have covered it, in the US Snow (as Cash would readily tell anyone) first made it famous.
