I'm on page 805, and I'm lovin' it. Of course, its my first Beatle book, so I really have nothing to compare it to. So far, from being a member of this Forum, I haven't run across any contradictions. And no, I have not clicked on those links. Maybe I'll wait until I'm finished with the book.
I've read Here, There, and Everywhere by Geoff Emerick, which is a Beatle book, of course, but not exactly a bio. More of just a collection of opinions, as if you were reading his diary.
