“Morality and love and pork chops”: The roots of John Prine’s “Tree of Forgiveness”

John Prine already has concrete plans for the afterlife. "I'm gonna have a cocktail: vodka and ginger ale / Gonna smoke a cigarette that's nine miles long," he sings on "When I Get to Heaven," the final, rollicking track on stellar new album "The Tree of Forgiveness," due out April 13 on his own Oh Boy Records.
