Yes I saw this last year on TCM & it was worthwhile for the music parts. I had forgotten the name of the title, usually they show these marginal items in the middle of the night so have your dvr ready.

Interesting they also showed, later that year, a Brit film about the traditional jazz movement that was sweeping England's campuses at the same time that the folk "scare" was happening in the states, "It's Trad Dad!"
