David said John Lennon gave him the advice he needed to move on. "John Lennon said to me, 'You now need to begin what I've been doing—which is demystification,'" he says. "If anybody knew, he knew. And because I respected him and I grew up, he was kind of my hero, to become friends with him and to also know him and to know and to see him evolve 10 years later—he called himself a house husband. And for me, it had such an impact."
Eventually, David says he was able to overcome the face that was plastered across lunchboxes and magazine covers and start new projects. "It took me about five, seven years, and I began working in the theater," he says. "I went back and tried not to compete with my fame."
