Joshua Wolf Shecnk in the Atlantic takes a look at the collaboration - and non-collaboration - of John and Paul, making the case that, even if the duo wrote most of their songs independently, the partnership still greatly influenced how the Beatles' songs turned out.
The diplomat and the agitator. The neatnik and the whirling dervish. Spending time with Paul and John, one couldn’t help but be struck by these sorts of differences. “John needed Paul’s attention to detail and persistence,” Cynthia Lennon, John’s first wife, said. “Paul needed John’s anarchic, lateral thinking.”
Paul and John seemed to be almost archetypal embodiments of order and disorder. The ancient Greeks gave form to these two sides of human nature in Apollo, who stood for the rational and the self-disciplined, and Dionysus, who represented the spontaneous and the emotional. Friedrich Nietzsche proposed that the interaction of the Apollonian and the Dionysian was the foundation of creative work, and modern creativity research has confirmed this insight, revealing the key relationship between breaking and making, challenging and refining, disrupting and organizing.
