I learned all those songs from my parents ("Goober Peas" is a particular favorite of my dad's). The only son I learned in school that I even remotely remember is "Ghost of John", and that just because I was into ghosts. I know I learned--I hate to admit this--"Eye of the Tiger" and "It's a Small World" in kindergarten but I can't remember them.
Question: how much folk (children's/patriotic/etc) music does the current generation know in comparison to the previous, and how much do THEY know in comparison to the generation before that? Is this a new phenomenon or is it something that has occurred bit by bit with each successive, increasingly media-oriented, generation, and we just now figured it out?
