“It’s not I’m going to say I’ll never go out and do another concert, I may. I don’t know. But I just don’t want to tour anymore, go through the travel, the stress and all of people’s perceptions that go up in this cesspool of [the] internet where anybody’s voice can be heard,” the 66-year-old tells Dr. Phil in an exclusive interview airing Tuesday. “It hurts me personally that a lot of my fans and a lot of people buy into it.”
