"While Mia Farrow inspired such men as Andre Previn, Frank Sinatra and Woody Allen, her sister Prudence left her mark on John Lennon. According to Nancy de Herrera's book, All You Need Is Love, Prudence met The Beatles on a spiritual retreat with the Maharishi in India, which she attended with Mia. When Prudence, suffering depression, confined herself to her room, Lennon wrote this hoping to cheer her up. It did."
