OK, cat out of the bag, I managed to read this book a few months ago, can't say how.
Everyone here should buy it, you will enjoy it.
However, unless you are a DS "get a lifer" it's not really a very interesting rock biography.
And for us obsessives, there are quite a few mistakes.
I also have it on very good authority that John did not write the book himself. I can't tell you how I know this and I can't offer any proof so you can choose to believe this or not, but I believe it to be true.
