As I remember McCartney had a blue collar upbringing. But again what would he be worth if the contracts back there were like they are modern day. Michael Jackson would have never owned the Beatles Catalog because Mac and Lennon would have. Not taking nothing away from Dre, He's done very well for himself.
i agree, except for one aspect. It was McCartney that showed Jackson the importance of owning music rights. Hence when the beatles rights were up for sale it created a huge rift between Jackson and McCartney since Jackson bought the rights.
McCartney originally went a different route with the beatles songs over ownership in the beginning...thus I don't think it would have happened regardless
