Johnny Cash's most emotional song, I think. He wrote it for June Carter, who died before the record was released. He loved her so much. He was once asked what his description of paradise would be and he answered that it was that morning having coffee with her. That's all it took. The wonderful thing about this song is that it's not some platonic love description, but it's him saying he's got a lot of baggage and a lot of mistakes that he can't take back, but he would, all of it, if it just would bring her back.
