Bill Harry thoroughly details all of McCartney's songs, records, tours, friends, pets, studios, producers and charities. It includes wonderful biographies of Linda and Heather Mills McCartney. You can learn about his many animal rights endeavors, his vegetarianism and numerous other charitable causes that he promotes. Every other Paul McCartney book is utterly incomplete. Bill Harry's comprehensive research is laudable, commendable and a must buy for any Paul McCartney fan.
