Johnny Cash is the only artist to have been elected to the Country Music Hall of Fame and the Rock and Roll Songwriters Hall of Fame. His hits include I Walk the Line, Ring of Fire, and A Boy Named Sue. By 1969, he had sold more records than The Beatles. The author interviews Johnny's brother Tommy, who provides insights into their childhood as well as a look at life on the road with The Johnny Cash Show. The book also includes interviews with Johnny's long-time manager Lou Robin, his producer since the early days Jack Clement, and artists Sandy Kelly, Narvel Felts, George Hamilton IV and V. Miller also carried out research at the Country Music Foundation in Nashville and talked to DJs Bill Black and Dick Barrie.
