I admit I haven't read the whole book, only excerpts. I also looked at the photos, some of which I've seen before and a few new ones. The excerpts I read didn't tell me anything new that isn't contained in other Beatles books (Hunter Davies, Philip Norman). I found two glaring errors in the photo captions. One photo caption purported to show George & Patti at Paul's 21st birthday party. Paul was born in 1942 and turned 21 in 1963. George didn't meet Patti until the Spring of 1964 while they were filming "A Hard Day's Night", contrary to another photo caption which claimed they met on the set of "Help" which was released in 1965. These are elemental facts known to most serious Beatles fans. If this author can't even get the photo captions right, how many errors is he perpetuating in the rest of the book?
