Ozarks - Taney Center Square #1
Footage recorded in Forsyth, Missouri, by Gordon McCann and shared with the Square Dance History Project. The fiddler is Bob Holt, recipient of the National Heritage Fellowship in 1999. The tempo is 153 beats per minute.
You can see different squares starting up at different times; at the start of this clip, the square in the foreground is just forming up when the others are already dancing. This is possible because each set has its own caller.
Note the distinctive jigging steps of the dancers, even at this very fast tempo.
