This is a reasonably entertaining trawl through The Beatles' mono catalogue.
It contains much in the way of the author's opinion but very little in established fact, which makes it a fairly useless addition to the existing canon of Beatles writings.
Most of the facts presented here have been dis-credited/ are rendered irrelevant, by thorough research - for example: does the author know 'why' the lead and backing vocals on the mono version of the Help! single are different from the stereo, or 'why' the mono sound is murkier than the stereo?
The answer is too complex to relate here but it would have been refreshing to have come across it in this book as it is one of the major events in the Beatles' mono/stereo story.
-Or how about the final guitar riff at the end of What Goes On?
-Or why the separation on those early stereo mixes is so wide?
For a more factual based approach (and a more worthwhile one), I would suggest that the author, and any potential reader, track down a copy of Mark Lewisohn's 'Complete Beatles Recording Sessions' or 'The Complete Beatles Chronicle'.
In addition, 'Recording The Beatles' by Kevin Ryan and Brian Kehew is a fascinating read, (and will tell you the answer to the Help! question too).
The reason I mention these books is that they contain between them about as much knowledge on The Beatles' recording sessions as is known. (Unfortunately the prices of these books can be quite high).
To finish, this is really only worth the bother if you're paying the Kindle price (and even then it should be no more than £1). Otherwise you'd be better off sitting down and listening out for the differences yourself.
If you've come this far looking for a book about The Beatles in mono, I heartily recommend that you seek out the books mentioned above.
