Ultimate shoulder rides

There is this one routine from the famous dance group PILOBOLUS called "the tall ladies", I wonder how long does the actual dance routine last, how long would these two ladies stay on the shoulders of the male dancer ponies, and how much time did they spend practicing the shoulder riding parts, it must be hundreds of hours!!! Wonderful
