The older Paul McCartney gets, the cooler he becomes. Now he's collaborated with Rihanna and Kanye West on the acoustic tune, "FourFiveSeconds."
"I'm four, five seconds from wildin'," the chorus goes. "And we got three more days till Friday/ I'm just tryng to make it back home by Monday morning."
Rihanna and West take the lead in "Redemption Song" Bob Marley style, and McCartney chips in background vocals and plays bass guitar. Download "FourFiveSeconds" here.
McCartney also plays keyboards on West's "Only One" track.
