Sheryl Crow wrote the song “Redemption Day” to put on her 1996 album as a political tube. However, when Johnny Cash recorded the same song for his album, American VI: Ain’t No Grave, just three months before he died in September 2003, he morphed it into a personal song.
Cash even called Crow on the phone several times asking about her emotions for the song.
"If he was going to sing a song, it was going to be a part of his molecular makeup," Crow said. "He was going to deliver it as if he wrote it. The questions that he asked and his concern for whether I would like what he was doing ... it was just really humbling."
As much as Crow has done in her career, that moment was the highest of her musical career.
"Actually, that's the highest honor I've ever had of anything in my whole life," Sheryl told Glamour magazine (quoted via CMT). "Him calling me and asking me, 'What were you thinking when you wrote this?' And him telling me about what it meant to him ... that was a true testament to him as an artist, wanting to be able to deliver a song and understand what it meant."
