We already know what New Directions will sing at Regionals next week: a pair of original songs.

As for the group's main competition? Along with a Pink single, The Dalton Academy Warblers will take on "Candles," a ballad originally sang by Hey Monday. Look for Blaine and Kurt to collaborate on the latter track.

And, next month, prepare to hear a lot more from these two and their Warbling mates, as Glee dedicates an entire album to the boys.
