Last music book I read was David Quantick's The White Album which is a witty and insightful look at the period and events around, as well as the music of the Fab's eponymous album. Quantick's favourite, but certainly not mine - for instance his opinion on O-Bla-Di-O-Bla-Da "If you do not like this song, you are an enemy of life and joy - you may be Lou Reed". Well I'm not Lou Reed, but he goes on to say "You may also be a Beatle", since apparently, McCartney aside, by the time they came to cut the number they all hated it.
It didn't take me that long... On the other hand I can hardly condemn McCartney as he also contributes 'Blackbird' - which for my dosh is possibly the finest 'simple' song of its era.
All that aside, I'd heartily recommend this book to any fan of the Beatles music or even student of the history of the era.
I used to be agnostic. These days I'm not so sure.
