[Callers] A Question on Thanks to the Dean

HI ALL, It seems to me that Steve Zakon-Anderson’s “Thanks to the Dean” has 3 progressions even though I know that it is a double progression dance. (A1) Allemande left below (1 ½ ) PROGRESSION #1 Ladies chain ( ½ ) (A2) Women Allemande Right once around and back to their partner All Balance and Swing your Partner (B1) Circle left about once and lead up or down the set to new neighbors PROGRESSION #2 Circle left with these neighbors ¾ around (B2) Dos-i-do this same new neighbor (who is now below you) (Does this mean that the circle left ¾ has “undone” PROGRESSION #2???????????) Allemande Right with this same new neighbor ( 1 ½ ) WHICH LOOKS LIKE PROGRESSION #3 ??????????? Can you straighten me out? I’ve checked the web site but it does not help with this. Thanks, Rickey Holt, caller Contra Dances in Exeter, NH P.S. I am hoping to use this dance tomorrow night.
