OK, move over, NKOTBSB! (If ya didn't know, that's the super-pop-group combination of New Kids on the Block and Backstreet Boys that's touring right now.)

Country music has Little Sugarland Big Town. Or Sugar Little Big Land Town. Or . . . well, you get the idea.

Sugarland and Little Big Town—which often tour together—have teamed up in the past for great covers of The Dream Academy's “Life in a Northern Town” and Marc Cohn's “Walking in Memphis.”

Their latest mesh is on Madonna’s “Like a Prayer.” They whipped it out in concert last week, and now you can see it on YouTube.
