I have called it twice thus far; both times the dancers enjoyed the dance - and the joke implicit in its choreography. Both times i used it in mixed-level situations, without problems, calling it as written. IMO it's a really good dance for introducing the "shadow" concept to inexperienced dancers because it's grounded in partner interaction - you simply turn your back on your partner and there s/he is! Also having a simple, straightforward progression mid-dance is to my mind a strength, because it adds variety to a program without introducing the higher complexity typical of mid-dance progressions.
