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memorabilia from New York to Los Angeles - photographs that had never been seen before, drawings, videotapes, poems, unpublished songs and other writings. The Lennon family in England also provided previously unpublished photographs.;The text of the book is entirely made up of unpublished writings by John, while Yoko Ono has made the book a personal tribute to John by writing the introduction.
