That video is of the third instance, FYI. The camera is placed halfway up the hall on the fireplace mantel.
BTW the videographer, Frank Hsieh, can be seen in the lower right corner starting at 0:15 or so (white shirt, close cropped hair). He makes extensive recordings of the CSH dances which Chris so helpfully tags with titles.
