-DonIn this instance the difference between the calls was very significant. I called a RA but the dancers (mostly) did a RAHS. This was in a box configuration, meaning the dancer pairing became opposite to what was intended. The next time I call this dance I will be sure to say "Roll Away BUT NO Half Sashay, Gents stay put".I ran into this a short while ago while calling a new (to me) dance and having the walk-through fail. I knew the dance was right and my instruction was correct. Rather than try to figure it out on the fly I bailed to a fall-back dance. As I video most of my gigs, I was able to go back to that and see what happened.Of course, this can be also done in other configurations like circles and boxes.Ending position G0 L2|G1 L3|G2 L4Starting position G0 L1|G1 L2|G2 L3"Gents Roll (Away) the Ladies" (Ladies only change position):In my understanding, the two calls are like this (the "|" symbol denoting the boundary between adjacent hands-four):I have to respectively disagree here.In my experience, a "roll away" (RA) call has been conflated with a "roll away with a half sashay" (RAHS) for many dancers (and callers) - but the moves are distinct and can have choreographic significance. What I think has happened is that callers are using abbreviated calls of something like "roll" for the RAHS situation (which is more common) and that has colored the interpretation.
