I agree with the above, and understand Paul very well. Why not claim what is yours? And show the world that it was you who did it. But in our striving to establish the truth we sometimes overlook the fact that it might look more like making a fuss than doing a heroic deed. And, i doubt that he got any satisfaction when he had achieved the aim. (Because everybody noticed it and remarked on the reasons.)
I quote: "Bob Geldof, a huge admirer, but one infuriated by McCartney`s defensiveness about who was the "groovy" Beatle, once told him, "There is no greater achievement in the 20th century to beat what you and your mate did...there are the great artists, you`re one of them. Relax!"
I love you, Paul!
