A vivid, captivating account of the Beatles’s musical transformation throughout the pivotal year of 1963, as the world became caught up in the maelstrom of Beatlemania and its far-reaching cultural impact. The Beatles broke up more than half a century ago, yet millions around the globe are still drawn to the legacy of four lads from Liverpool. From the carefree innocence of "A Hard Day's Night" to the experimental psychedelia of "Lucy In The Sky With Diamonds,” their message of love, peace, and hope still resonates. In Shake It Up, Baby! we go back to the start—to 1963, when they went from playing in small clubs in the remote Scottish Highlands to four number one singles, two number one albums, three national tours, and being besieged by thousands of fans at gigs all over Britain. Ken McNab tells the story through gripping, exclusive eye-witness accounts from those who were there: the Beatlemaniacs, the journalists, broadcasters, and television producers who were scrambling to make sense of it all—and the other bands who could only watch in awe as the Beatles went from bottom of the bill to headline act to the biggest band on the planet, forever transforming musical history.
