Former Beatles Paul McCartney and Ringo Starr will reunite on stage next month to raise money to teach transcendental meditation to children around the world to "help provide them a quiet haven in a not-so-quiet world," McCartney said. The star-studded list of performers who will join them include two musicians who were with the Beatles when they journeyed to India’s Himalayan foothills in 1968 to learn transcendental meditation from Maharishi Mahesh Yogi. “In moments of madness, it has helped me find moments of serenity,” McCartney said in the concert announcement
