Dancers start in two lines facing up.
⇐⇐ ⇐⇐ 1 4 8 5 Music ⇓⇑ ⇐⇐ ⇐⇐ 2 3 7 6
Dancers 1 & 2 move toward music and cross (passing right shoulders). When dancers 3 & 4 reach the same spot, they cross passing left shoulders. Continue in a grand right & left (twice around), ending up in home positions:
2 4 6 8 Music 1 3 5 7
(If dancers arrive home before the end of the music, twirl/spin in place.)
