Fueled by archival film clips and captivating anecdotes from friends and family, this unauthorized biography of John Lennon captures a lesser-known side of the Beatle who caused as much a stir with his personal causes as he did with his music. Highlights include rarely told stories about Lennon's upbringing from his half sister, Julia Baird, and tales from former members of Lennon's first band, the Quarrymen.
