 or if the dance gets off synch for any reason.  It can also signal that the
 particular tune, or arrangement, might be confusing to dancers.

That's one of those cues that you don't need often, but when you do, 
hoo-boy is it useful!  I'll try to remember to add this to my pre-game 
chat with the band.  I've certainly needed it a couple of times, but 
haven't had the sign-language vocabulary to express it.  Thanks for 
providing that, Greg.
