The 65-year-old crooner made a remarkable comeback last year when he paired with producer Rick Rubin–better known for cultivating hits for the Red Hot Chili Peppers and Metallica–to produce “12 Songs,” which sold 514,000 copies in the U.S. to date. According to the Recording Industry Association of America, Diamond has sold 48 million albums in the U.S. over the course of his career. Diamond’s tour was one of the highest grossing last year, trouncing more contemporary acts like Green Day and Coldplay.
