Ed Sheeran

Ed Sheeran's stock has risen just a wee bit during the past few years—a couple of platinum albums here, a sprinkling of Grammy nominations there. Earlier this year, the ginger-mopped British folk-pop star played the Grammys with a no-big-deal assortment of players including John Mayer, Questlove and E-L-freakin'-O. We can't promise guests of that caliber here, but it wouldn't surprise us in the least if a few big names turn up to help Sheeran support his strummy 2014 opus, X.
