But Rossi tells Classic Rock: "To me, the tour was a f**king mess. Spud was unfit and kept slowing down, and Alan has his own problems. So it was extremely hard work for me and Rick."

He also admits to feeling bewildered over why anyone cared. "Sometimes it was so sloppy that I can't see why the fans loved it. I'm glad they did, but for the life of me I can't comprehend why – other than it's all about nostalgia. And that's not really what motivates me."
