Getting the tracks for the Johnny Cash tribute album wasn't a collection of covers, claims Marty Stuart.

The producer of last year's Grammy-winning tribute to Hank Williams said put together Kindred Spirits: A Tribute to the Songs of Johnny Cash was the work of artists.

Bluesman Keb Mo' contributed a truly original take on "I'm So Lonesome I Could Cry," for "Timeless," the Williams tribute album.

But when Keb Mo' was studying "Folsom Prison Blues" to find his interpretation of the song for Cash's tribute album, he called Stuart.

He told Stuart he loved the song, with one exception. He didn't like the lyric "I shot a man in Reno just to watch him die," it turns his stomach.

But Stuart had worked with Cash on a Bruce Springsteen tribute, where Cash changed The Boss' words to "I'm on Fire."

So Stuart suggested Keb Mo' do what Cash did -- change it!

Bob Dylan, Bruce Springsteen, Little Richard and Dwight Yoakam also sing on the Cash tribute.
