I Bought David Quanticks Revolution*, and although his sharp opinions and often lame-wit sometimes annoys the reader more than anything, I thought the information of Charles Manson was well-researched and generally interesting.
Some of the information, such as Vietnam etc was brief to say the least, but for me (using it as a research piece for my work), the design factor was alot more detailed than the anthology book, and well written.
Evaluations on such songs as Rocky Racoon are just absurd, and I totaly agree about the blatant personal views been edged in anyway possible.
Its not terrible, and not Gospel.
Like most Beatles Books, it needs to be taken with a pinch of Salt.
