All You Need is Love, or How to Tanscend a Happy Marriage

In 1967, the Beatles released what was arguably their sappiest song: "All You Need Is Love." It became an anthem of the hippie era -- encapsulating the sentiment of the San Francisco Summer of Love -- much the way "We Shall Overcome" became an anthem of the slightly earlier civil rights movement.

The notion that love can conquer all is back, in the form of a play by Sarah Rhul called "How to transcend a happy marriage" that is currently playing in New York at Lincoln Center.
