Soulful dudes Sam Smith and John Legend have both been having a great year. Smith cleaned house at the GRAMMYs, winning four with his debut album, In the Lonely Hour; Legend took home the prestigious Oscar for Best Original Song with "Glory," the stirring song from Selma.

Now the two have hit the studio together for a new version of the 22-year-old Brit's "Lay Me Down." Rolling Stone reports that "Smith and Legend will perform their duet live for the first and only time on March 13th at the live Comic Relief: Face the Funny special at London's Palladium." The event is a tie-in with Red Nose Day, one of Comic Relief's two biggest annual fundraisers. The organization, which was founded 30 years ago, works "to tackle the root causes of poverty and social injustice in the UK and across the world." Read more about its mission here.

The BBC quotes Legend as saying, "Sam is such a talented artist. We've been looking forward to working together for a while now. I'm so glad we could collaborate on such a great song and for such a great cause." 

The collaborative version of "Lay Me Down" is available on iTunes, with all proceeds going to Comic Relief.
