Paul McCartney and Kanye West at the Grammys in 2009. If this track's any gauge of what's to come, Paul McCartney and Kanye West is a match made in heaven. Kanye's singing, Paul's on the organ. According to Stereogum, "Kanye and Sir Paul started recording together early last year in a Los Angeles bungalow with McCartney improvising on keyboard and West improvising on vocals." Kanye says this about the lyrics of "Only One": “My mom was singing to me, and through me to my daughter.” The poignancy of that surely wasn't lost on McCartney.
