With all of the words that have been written about the Beatles, both collectively and individually, I usually find myself asking if there's really a need for yet another book about them. While there have been many excellent well researched and well written books on them, those are vastly outnumbered by others that are little more than cash-in hack jobs. However, from the minute I heard about Lennonology several years ago, I knew it would be in the former category.
