The story of "The Beatles" - without a doubt, the No. 1 group in world pop and rock music - is primarily the story of four simple Liverpool guys who turned the consciousness and life of entire generations upside down. Alan Clayson, authoritative music historian and columnist, "pop couturier," former rock musician, presents in this book a detailed biography of John Lennon - the leader of the group, guitarist and keyboardist, one of the main producers of music and lyrics "The Beatles," the author of the famous hippy anthem "All You Need Is Love" and the incredibly deep song "Imagine," a stinging mockery and a fierce fighter for world peace.
