Defining behaviors and drivers
John was the epitome of a high-D, low-S/C, driven to accomplish much, but always in a hurry to finish whatever it was so he could move to the next thing. Definitely lacking patience, John wanted everything to be done as quickly as possible. John never cared much for rules and followed only those rules that seemed to suit him. He was charismatic and people were always drawn to him, which is indicative of someone possessing at least a relatively high-I. Comparing the behavior of John and Paul, they were mostly opposites.
Both men enjoyed the spotlight, but Paul would defer to John on occasion, such as when standing on the Ed Sullivan stage after their performance, when there was only room for one Beatle on the higher platform. Other times, John would step back and let Paul have his moment, usually to the delight of the screaming girls in the front row. They realized they each brought their own value to their audience, to the overall benefit of the band, so they adapted their behaviors accordingly and willingly shared the spotlight.
Switching roles
For a new challenge, the two occasionally spent time reversing roles. John was known for his rockers and Paul for his ballads. However, toward the end of the union, Paul penned the very raucous, Helter Skelter, while John countered with the touching soft ballad, Julia, a tribute to his deceased mother.
What it all means
Most people will argue that Lennon and McCartney were more successful together than as solo artists, and rightfully so. Together, the two created a force that far surpassed what they could, and did, accomplish individually. With a unique balance of collaboration and competition, the two pushed each other to continuously raise the bar and exceed even their own expectations.
While Paul may have been the band’s unofficial “musical director,” he and John took turns running the show. Early on, John and Paul may have deferred to the mastery of their experienced producer George Martin. As time went on, they took turns calling the shots for various album sessions. Paul was widely known to have controlled the majority of the Sgt. Pepper sessions while John reasserted his leadership during the tumultuous White Album sessions. Both albums are considered brilliant by critics and fans alike.
As a unit, The Beatles seemed to have a natural ability to channel the exact behaviors and drivers needed when they were needed. When John lost focus, Paul took control. When Paul began to lose interest, John took control back. Finally when conflict between John and Paul was making it difficult to accomplish anything together, George Harrison stepped out of the shadows, asserted control and delivered some of the bands most iconic songs as showcased by their epic masterpiece, Abbey Road.
There was a perpetual give and take, push and pull, that made The Beatles work. John and Paul were clearly each other’s yin and yang. The complementary behaviors and drivers closed all the gaps and filled all the holes, making The Beatles an unmatched force in the music scene, something the world hasn’t seen since.
