They were just ordinary lads! How come they become a couple of geniuses? Lennon and McCartney: (1) had a deep passion for music and girls and Life; (2) wanted to be best in their field; (3) had talent which could be developed once the hours were put in; (4) wanted to lead not follow; (5) enjoyed being different; (6) experimented with everything from drugs to multi-track machines to full orchestras to meditating; (7) had encouragers such as Epstein and Martin; (8) were needed by a post-war Britain to bring hope; (9) rode a wave of social unrest; (10) broke all the rules of popular music; (11) didn't care about what others thought; (12) discovered the studio as laboratory; (12) became directors of their art from lyric to album cover; (13) understood language as more than just words; (14) created a high performance team; (15) did the ground work in Hamburg and empty gigs in Southampton. But above all else: most clearly, magically and ultimately tragically: they had each other. That's why they became a couple of geniuses.
