Here are a few:
Amy Asked for a Gypsy (Charley Harvey)
Balance to my Lou (Becky Hill)
Maliza's Magical Mystery Motion (Cary Ravitz)
Square Thru to You (Bob Isaacs)
The Wise People of Chicago (Bradley Smith)
BTW, in a medley, you can change directions (becket-L to becket-R) if you
also flip which side of the set the dancers are on, but only do this once.
(E.g., the first time through, swapping circle left 3/4, N swing for a
gents allemande left 1+1/2, N swing.) As long as dancers continue to
progress to new neighbors up/down as before, they won't come back to
previous neighbors.
