There was a click between Paul McCartney, John Lennon, Harry Nilsson and Pete Hamm that just created some wonderful songs. Harry also had a voice that could soar. He and Ringo used to be a riot when they got together. Harry was an introvert but, in a one on one situation, he was a blast. You can find humor across the songs he wrote. Satire. Great imagery. Introspection. Harry was an introvert who found his voice through his songs. My wife and I have been fans since the very beginning.
