It's never too late to form totally random associations. Last month I reread Lord of the Rings and also listened to an opera compilation I've had for ohh 25 years? And now when I hear Puccini's Ch'ella mi creda, the totally ear-wormy aria from Girl of the Golden West- but of course, all Puccini is ear-wormy- I see in the background what I think is Lothlorien, which I must have been reading at the time. Can't pin it down more than that: it's shady trees and possibly elves, which means not Rivendell. And it's not exactly annoying but is a bit... intrusive.
