“Kilgore went on to a career as a country music recording artist but had great success as a songwriter, co-writing with June Carter the song "Ring of Fire", first recorded by her sister Anita Carter and later by June's future husband, Johnny Cash (Kilgore was a distant cousin of the Carter sisters through their maternal grandmother, Margaret Kilgore Addington); June, later known as June Carter Cash, would record her own version of the song for her album Press On, released in 1999. He also wrote Claude King's big crossover hit, "Wolverton Mountain". Amongst others, he also penned "Johnny Reb" for Johnny Horton and the Tommy Roe pop music hit, "The Folk Singer". In the early 1960s, he toured with Cash as part of his package show. He stood as Johnny Cash's best man at his wedding to June Carter.” Wikipedia
