Spud, the fact that you are taking an interest in this is a sign that you don't have Alzheimer's. My father is in the early stages, and one of the symptoms is (apparently) a loss of interest in things. So keep kicking, and get down (paper, computer or tape) those esoteric things, no matter what they are, or they won't get passed on and they'll be lost forever. I'd hate to see that happen.
