If Charles Lindbergh represents a technological revolution, the Beatles represent a revolution of style. In an attempt to grasp the cultural explosion that was the Beatles, watching A Hard Day’s Night is a good primer. Basically, everything surrounding the Beatles in the movie is old, dull, stodgy, square and authoritarian. The Beatles themselves are young, charming, charismatic, fun, sexy, silly, improvisational, with long hair, irresistible harmonies and a beat you can dance to. Such things can make a revolution, and did. You hear it in the ecstatic screams of the audience. Revolutionaries break facades that open the awareness of your senses and, in Beatles’ parlance, or in William Blake’s, free your mind. All you need is love, and a pair of cool boots.
