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. In Shake It Up, Baby! we go back to the start - to 1963, when they went from playing to a handful of people in the remote Scottish Highlands to four number one singles, two number one albums, three UK 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 TV 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 biggest band on the planet.
