What about the reports of the numerous typos, like "Marvin Gay"? And what I've seen described as Dean's pride in the Budweiser sponsorship which gave fans "Be True To Your Bud" with Mike along with a college tour in the early 80's, behind a song (more or less) which is an abomination? From scanning other reviews I've also seen quite a bit of distaste among fans for the way Jan is talked about in the book. Just curious, I do not have a copy yet so I'm only speaking from the reports and other reviews of it.
I found the misspelled names to be curious. There were a number of them. "Mike Dasey" [should be Deasy], for example. There were enough to where I wondered if they were misspelled on purpose, but I know of no reason why that would be the case. Those are the kinds of mistakes that an editor at a publishing house, who has no knowledge of the subject matter, will not catch. It would take a proof reader with knowledge of the subject matter to catch those. But aside from the names, Dean's book is not poorly written. Readers and fans can question the content, to be sure. But it's a conversational read.
As far as Dean's treatment of Jan in the book, it did not surprise me. But I'm more familiar with their dynamic than perhaps many Beach Boys fans. There's really no fixing the rift between Mike and Brian, and I believe the same is true for J&D. I was actually hoping for more insight on their differences during the original era, but we didn't get it.
Dean was really into the Anheuser-Busch thing with Mike. Jan was touring with his own band called Aloha while that was going on. That's covered in my book, but not Dean's. Jan didn't lose a beat on that while Dean went off to work with Mike. And Jan kicked his drug habit so that he and Dean could earn the bigger paydays by performing together. He had plenty of incentive there.
For readers interested in learning about Jan, I humbly suggest that they read my book.
