This book is unbalanced: only a few final pages sum up his post-Beatles years. What an unforgivable blunder!
It is also poorly edited: the author's comments are not particularly good, detract from the text, and hence were annoying.
This book smacks of exploitation of the anniversary of a good man's demise. Do not reward them with your hard-earned money.
I saw the Martin Scorsese documentary on HBO and it is superb! I recommend that, and the book by George's wife, Olivia.
