The saga of one of the least expected collaborations in musical history continues with the video rollout for 'FourFiveSeconds', the enjoyable product of a partnership between Rihanna, Kanye West and Paul McCartney.

In the plaintive, black and white video, Rihanna and Kanye sing while an unassuming McCartney, hardly looking out of place, strums along with the youngsters on an acoustic guitar. It's a serious departure for Rihanna and West and will apparently appear on both of their next albums. The song will also be performed live at the Grammys on February 8 by all three musicians.

McCartney also played keyboard on the recent Kanye track 'Only One.' We're not sure if we can expect more from this apparently fruitful union of the new and old schools, but for now we'll enjoy what we have. See the video below!
