What was the meaning of this JEOPARDY! category?

I didn’t get it at all. Am I just dense?

In last night’s “Tournament of Champions” episode of Jeopardy, the first category in the Double Jeopardy round was titled “JEOPARDY!/KEYWORDS… NOT!” (Instead of a slash, it was a horizontal line beneath “JEOPARDY!”) Alex warned the players, “Be careful of this category!”

The clues in that column just seemed like random bits of trivia; no clever wordplay or any connection between the answers that I could see.

What was I missing?

Hmmm… I went back and looked at all the clues again, and I guess it fits. But I - like most people, I’d wager - knew instantly that “Band on the Run” is not a Beatles song, Wisconsin doesn’t have a Central Valley, and Sousa wasn’t British. So I wasn’t getting that the clues were meant to be misleading.

Interesting idea, but I clearly wasn’t the only one left scratching his head.
