Tune in, the first volume of a biographical trilogy by Beatles historian Mark Lewisohn, takes the Beatles from before their childhoods through the final hour of 1962--when, with breakthrough success just days away, they stand on the cusp of a whole new kind of fame and celebrity.This is the lesser-known Beatles story--the pre-Fab years of Liverpool and Hamburg--and in many respects the most absorbing period of them all.--From publisher description.
