Haha..yea i was always the same way growing up. It's such a memorable piece that literatlly everyone recognizes it the instant it hits their ears. Now as far as your question goes..I know that adults sitting in an opera theatre seeing this piece live is definitely going to have a greater effect on them than a kid or child just watching cartoons. Because by then you know so much more and can appreciate it that much more for what it really is, one of the most genius pieces of music know to man.
