I've studied this topic with great interest over the last couple of years, and the conclusion I've come to is that James Paul McCartney changed
somehow in the fall of 1966. HOW he changed, I'll never be certain, but I'm satisfied with my conclusion, because the myriad photos, videos and text
I've seen display a different personality (dare I say SOUL) took over around that time.
It's all in the mens' eyes. That's how I can tell them apart. It's not about color or shape, it's about the PERSON inside the body...and to me,
something is very different. The essence of the individual is not the same...whether James Paul was replaced, I cannot say. But something dramatic
took place and I don't believe it's as simple as growth, drugs, weight-loss, or any other benign reasons/facts/suppositions I've read.
And not to put down any of the research done, which I presume was done in its majority by men (correct me if I'm wrong), but as a woman, a couple of
my girlfriend's believe the same. The
person behind the eyes is different and that's how you know that JPM and Faul are not the same man.
