In the years since getting famous, John has started a family, battled cancer twice, and along the way, gotten more comfortable with being known. His new album is The Tree of Forgiveness—and it's brought him the best album sales of his career. To get it written, John told me, his wife and stepson sent him to a hotel room in Nashville and told him to get to work. "I would knock around during the day and go get a hot dog," he told me about his writing process. "And at nighttime, I’d start writing about three in the morning, order room service up, have a party by myself and end up with a couple songs every day."
