He MOSTLY raised himself from the age of 10 onward and never had a strong male influence in his life...well, except for those fellas singing on the radio, something he very early on learned he could do as well, if not better than them.
By the time he was 19 he was "nearly famous" and by the time he was 25 he was the most recognized man in the world.
Nobody ever told him "no".
How could he not be totally screwed up in the head?
But, dam he could sing. A melodic genius.
Unfortunately the problem with John Lennon is that anyone listened to anything he said. He had some talent as a musician, it’s a shame he was murdered, and he said some pretty outrageous things. I remember pretty clearly. No one should take entertainers seriously as anything but entertainers, but unfortunately they impact the culture because stupid people look up to them as role models and believe that because they can sing, or write music, or act or whatever, that they have some sort of great insight. And of course, most of them are no smarter than the average person, and many of them are far less insightful and quite a bit more self absorbed.
