This came to me after a trivia question that was right up my alley on Tuesday. This may be one of my better puzzles. I think the theme and mechanism is clever and there are other hints to the answer that you may be able to guess without even doing the meta. I hope it all works and blends together.
Other then necessary theme entries there are no "woozyism"s; there was one short one but I decided to replace it with a "How the hell are we supposed to know that" clue (You aren't, but you should get the cross entries and make educated guesses at some letters and you can use St. Wikipedia to verify afterwards ... or just google from the start, no-one's judging you). There are a total of 3 of those in this puzzle which if the cross entries are clear is, I believe, an acceptable number. (You may replace one clue with the woozyism "Was it the 16th letter?" if you prefer)
