When work started on this book, Yoko Ono freighted two boxcars full of John Lennon's personal memorabilia from New York to Los Angeles - photographs that had never been seen before, drawings, videotapes, poems, unpublished songs and other writings. The Lennon family in England also provided previously unpublished photographs. The text of the book is entirely made up of unpublished writings by John, while Yoko Ono has made the book a personal tribute to John by writing the introduction.
