Paul McCartney and Kanye West are maybe collaborating

Kanye West and Paul McCartney might be recording together, if The New York Post is to be believed. The Post says its sources confirm that West and McCartney have been working together on a number of tracks—including one called “Piss On My Grave.” So far, these tracks are said to be kind of amorphous, but The Post claims they “could develop into an album.” West’s reps have declined to comment.

For what it’s worth, West was at McCartney’s concert last week in Los Angeles, and McCartney said last year that he was interested in collaborating with either West or Jay Z.
