Query: Simply Superb !!!!

In a Beatleworld where millions of words are written about the gods, some of the best find their place in this absolutely indispensable book. Well researched, thought out and tastefully crafted, this book is a must in any serious fan's collection. I'd like to thank Amazon for making this book available to me after years of wait. And after reading it I can vouch it was well worth the wait.
