The book is an interesting read with a handful of startling and unexpected insights peppered through its pages. Not quite the scandalous alternative view that it makes out, but there are some juicy titbits that you may not have come across before - the fact that John disliked Yoko reading Japanese books and magazines because he felt it was part of her mind that didn't belong to him; the fact that a junior George used to follow John and Cynthia everywhere, even on dates; the fact that Mal Evans co-wrote a number of songs on Sgt. Pepper.
HOWEVER - and this is a big however - I found the huge amount of typos and mistakes very distracting. The book was originally published in 2000, I bought the 2007 version, and no one had been through and cleaned it up in the meantime. Lot's of example's of apostrophe's being used in plural's - a cardinal sin. Wrong words dotted about, rendering whole passages baffling, a product of lazy transcribing. Spelling mistakes. You name it.
So, definitely a book worth reading, but if you're annoyed by professional writers using sloppy English, this isn't the one for you.
