Paul should open up the Paul McCartney Museum and show case all of his professional talents. It should encompass a library, a learning center, a workshop, a recording studio, and a giantic museum. He should open it up somewhere either in England or in NYC and it should be set up like GRaceland where it can generate revenue.
If there are Presidential centers and libraries, why not something for music it means more to people?
The seed money would need to come from fans and from Macca's large pockets. Of course, i'll set up a business plan where John Eastman will see it will make back money in five years and most importantly seek to promote and encourage the McCartney BEATLE LEGACY. I think that means more to McCartney than dollars and cents.
I'll be glad to join the MPL Club as curator. My first task is to set up a place where all people can hear the Pepper masters on their original four tracks with just vocals, bass, and minimal backing. A place where Beatle nut jobs like me can hear the 27 minute version of Helter Skelter. But, i recommend sitting up the board with his kids, a few beatle insiders, and a few objective rock n roll historians.
