January has been a Dance Party around here for a long time. This particular classic is from 20 years ago, so just think how silly we’d look now. The cartoon does beg a question. At the height of folk music’s popularity, in the time of the “beatnik,” did anybody dance? I vaguely remember this period, as I was a very young boy. I remember watching on television trios or quartets of earnest, squeaky-clean young people singing mostly ballads; it would have been like dancing to a book reading. I have never been a fan of the cinematic “mockumentary.” Their humor is a bit too droll for me, and that’s saying a lot. If I have a favorite mockumentary, it would be “A Mighty Wind,” which treats the folk-music scene. That’s not to say I don’t appreciate folk music today. I do, but in manageable doses.
