From the Saturday Stumper

Today’s Newsday Saturday Stumper is by Lars G. Doubleday, aka Doug Peterson and Brad Wilber. I didn’t think I would finish, but I did. One clue that I especially liked: 14-Down, nine letters, “Company function.” No spoilers; the answer is in the comments.

[“Lars G. Doubleday” is an anagram, not of “edgy sour ballad” but of the names Bradley and Douglas. See these comments on a 2013 puzzle.]
