Notes:
- I imagine they all have quite a few things in common, but in each case I'm after something in particular. As is usual, the quizmaster's decision is final.

- each set has something different in common. One is reasonably easy (IMO); the other two, not so much.
Clues will be forthcoming as necessary.
