Soulful crooners John Legend [1] and Sam Smith have collaborated for a duet of Smith's "Lay Me Down" in honor of Comic Relief's Red Nose Day, which is this Friday, March 13. The music video has been released, and it really is quite emotional — perhaps even more than the original [2]. Smith and Legend are recording in the studio, while footage of young children playing and smiling is shown. The charity was originally founded to support children who are victims of famine, mainly in Ethiopia, which makes the video all the more poignant. Take a look.
