1966: the most manic of the Beatlemania years. The lads get chased around the world, playing 25-minute sets that have nothing to do with the increasingly complex music they're exploring in the studio. A long-forgotten John quote about religion – "We're more popular than Jesus now" – gets dug up and creates a scandal in America. A Ku Klux Klan protest outside their Memphis show draws 8,000 people. The butcher cover gets censored. The drugs get heavier – Paul dabbles in cocaine, John dabbles in acid.
