ONCE A NIGHT (or, YE SOCIAL POWERS)  1774
Barnes.  Meter: 6/8, Key: ?
3-couple set, tune structure AABBC 
(C sounds a lot like a repeat of A but isn't quite) 
via Lise Dyckman.

A1: 1-4:  1s leisurely cast into middle, 2s leading up at bar 3. 
          (which is clear in the music, incidentally)
    5-8:  1s and 3s circle once around.

A2  1-4:  1s cast back up to the top (2s wait and lead down);
    5-8:  1s and 2s circle once around [timing ditto].

B1 & B2: 1-16:  crossover mirror hey, skipping 
                [usually danced with only cu 1 crossing on the first pass, 
                but could conceivably be /each/ cu crossing  when they get to 
                the top]

C: 1-8:  track figure [brisk!]: 1s lead down center below 3s, 
         cast up around  them into the middle, lead up through 2s at top 
         and cast to bottom 

         [no one moves up until they're casting to bottom, 
         otherwise there's no time.  That cu 1 doesn't rest at bottom - 
         they become new cu 3 and circle in next A1.]
