Never seen before footage from the 1960 Newport Jazz Festival where the Dave Brubeck Quartet play "I'm In A Dancing Mood" commencing at 3:27 of the clip.
The You Tube video also has footage of Nina Simone, Gerry Mulligan and Maynard Ferguson. The narrator for the show was the legendary Wallis Conover.
Also posted is a video from 1974 that went missing from You Tube some time back. Thankfully it has now been re-posted. It is from a German TV broadcast of Two Generations of Brubeck. They play a wild and wonderful version of Circadian Dysrhythmia.
