Yoko Ono
When Sean Lennon grew up, he also became a musician. He helped Ono to compile (collect and put in order) her old recordings, and make some new ones. She also revived some of her earlier artwork, and gave the money made from sales and exhibits to charities. Ono recently (2006) appeared at the opening of Love, a Cirque du Soleil show featuring Beatles music, to help promote it.
