@vivdunstan Thanks for the link. That really was tough, but a fun challenge.

Quite pleased to dredge enough out of my memory to reach 21, although some were little more than lucky guesses. But also saddened to know that 30-odd years ago when I was properly obsessed I'd have quickly and confidently hit 27+. I can only hope that all the stuff I've forgotten has made way for more important things than Middle-Earth trivia...
