Too funny! I was thinking the same thing before I read your post.
As a young child in the 1970's, I remember the hippies with their guitars and tamborines doing all the refrains at the Folk Mass. Even at the age of six, I remember disliking it and thinking to myself "there is something wrong here..."
How the bishops were so clueless is beyond me. I have yet to find anyone from that era who actually liked those Masses.
