Hunter Davies is a great writer who has been lucky enough to write about some fascinating subjects. But none better than the Beatles.
His research centres in 1967-8, with the Beatles at work on the White album and it's a sort of glossed picture. For example, he doesn't go into John's infidelities - he is still the family man here - nor does he divulge all he knew about Brian Epstein, though he deals with this in the add ons to a later edition.
Yet even with this, he spent such a long time with them - and they obviously like him - that you get really intimate details. He is best on John and George -I think- and finds Paul the hardest to get to grips with.
This isn't the perfect biography, as he concedes: it's a bit like he never quite got on top of the mountain of material he accumulated, but it's totally readable and rich in detail. If you are interested in the Beatles, this is a gold mine, and it catches something of the Sixties London atmosphere too.
Even more to the point, loads of great books have been written about the Beatles since, "Revolution in the Head", "Shout" etc.etc. but no one except Davies had the opportunity to get this close.
You can read Lennon interviews or the Miles book on McCartney, but they are biassed. Davies captures them as they really were in the latter stages: his portrait is both perceptive and affectionate. A terrific book.
