Ed Sheeran Performs with Elton John

Maybe it is because my knowledge of modern music is lacking; however, I have no idea who Ed Sheeran is, and this combination of him and Elton John is phenomenal.  I have always had a soft spot for Elton John because he was my first concert almost 10 years ago at Madison Square Garden.  Nonetheless, in what seems like Elton John's 4,000,000th duet at the Grammys, this pairing of him with Ed Sheeran is yet another in a long history of fantastic duets at the Grammys.
