Outstanding. This is the definitive book on John and Paul. It is not the history of the Beatles, but a deep exploration of John and Paul's friendship and how that was channeled into their songs. By the time the book ends, you are not a friend of John or Paul but you feel like you know them very well and John's death, although you know it is coming, is a shock. Moreover, Leslie shows how John, Paul, George and Ringo changed culture and rock music forever.
