I have read Ken Scott's blog, and that's where I formed the opinion that he's a bitter man with ulterior motives -- jealousy, mostly -- and full of hot air. In his rant, he takes the position that he, and only he, knows the truth about what happened during Beatles sessions (even, supposedly, those that occurred long before he started working at Abbey Road, and long after the group canned him), and that's nonsense. Again, nobody else from those days has challenged the veracity of Emerick's book. IMO, the vicious way that Scott attacked a respected former colleague in public was incredibly distasteful, and I can well understand why the group chose never to work with him again after the White Album (though he did work on some of Harrison's solo work after they split up). As I said, Mark Lewisohn's book proves that Ken Scott had a whole lot less to do with the Beatles than Geoff Emerick did. That's why I mostly believe Emerick over Scott.
Of course, every memoir (in fact, every work of non-fiction) should be taken with a grain of salt -- that goes without saying. No one can remember with complete objective accuracy what happened yesterday, much less forty-plus years ago. But to argue that you won't "waste your time" reading a book that isn't 100% accurate -- and no book is, not even Mark Lewisohn's -- is to argue that nobody should ever read ANY book, period, which is a pretty silly position to take.
As a Beatle fan, I got a lot out of Emerick's book -- a lot of insight into how these four guys worked together and interacted with one another, as seen through Emerick's eyes. And beyond the fact that it was a great read, I think Emerick was a lot more forthcoming about them -- showing them as human beings, warts and all -- than many other similar books, so it was a valuable use of my time, making me indeed "wiser, at the end of the day."
We mustn't forget that all of these issues and stories are in shades of gray, not black and white. For example, the Love Me Do story cited by zipp. Yes, Emerick does tell an anecdote about George Martin suggesting that Paul sing the lead at the September session, and the Anthology release does show that Paul sang lead on at least one take at the June session. But that doesn't prove that Emerick was wrong. I think it's just as possible that in the intervening three months, the Beatles went back to having John sing lead (he was, after all, the most assertive in the band and it's entirely plausible that he instructed the others to ignore Martin's suggestion as soon as they left the confines of the studio) and that that's the way they again presented the song in September. I'm not saying that's the way it happened, just that it's the way it COULD have happened. So Emerick might be right about that, just as he might be right about many of the other stories in the book that some fans are so adamant he is wrong about.
