Interesting concepts in this thread. I have a friend who graduated with a degree in music, has performed oldies from pop music of the fifties and sixties. He is in his 30s and has an open mind for music in general. He heard our group play recently a set of old 50s and 60s "commercial" folk music, ala P Pand M and Kingston Trio stuff. He was totally unfamiliar with all of this music. Not that he didn't like it, he had NEVER HEARD IT! We performed twice this past weekend for great audiences and second set, we included a lot of singalongs of old hootenanny material (I know, groan!) The audience loved it! many said it was the first time in 30 years they had sung. The younger folks seem to enjoy it also, but are pretty much shocked that it was ever popular music in its time
