i just found this article from last year:
Kanye West could possibly have new music with Sir Paul McCartney in the works. According Daily Mail the rapper wants to work with former Beatle on his upcoming album. The musicians have reportedly been good friends for years. In an interview last year McCartney revealed he is indeed a fan of Yeezy’s music and would love the opportunity to work with him. He even bought Watch The Throne.
“Kanye and Paul have known each other for a long time but have become more friendly recently. There’s every chance they’ll head into the studio together,” an insider told the Sun. “Kanye really respects music legends and is still putting the finishing touches to his new album.”
this is so cool. i never really expect old white men to understand current hip-hop (even some of the old black folks don't understand it sometimes), so this is really a big surprise to me. makes me wonder how John would feel about Kanye if he was still alive.
