Hunter Davies, columnist for the Sunday Times, signed an exclusive contract with the Beatles in 1966. He subsequently worked with them for eighteen months on this only authorized biography, which became a worldwide bestseller. Since then, a multitude of books has been written about the 'Fab Four', but Hunter Davies' book remains the only official biography, detailing the world in which the Beatles lived at that time. The author maintained friendships with all the band members, mingled in their circles, and was able to document the course of their solo careers and personal lives firsthand up to the present day.
