I remember this fic that I read over on Fanfiction.Net a couple of months ago. Kurt was as Dalton and he and Blaine were together and together they sang 'First Dance' by Never Shout Never. It was sung at either regionals or sectionals. I know it's not much to go by, but I hope someone can find it for me. I'm pretty sure it was chaptered and the part that I remember is just part of a chapter.
