CNN's Jarrett Bellini talks to the Rolling Stones' tour manager about juggling and public speaking. "We need jugglers or you're lack thereof," says Mick Jagger's tour manager, who is also a professional juggler. The pair performed at Nebworth Rock Festival in front of an audience of more than 100,000 people. 'I love that when you're juggling, your skills are on full display,' he says.
