Tune: Frank Palmer
Four-couple longways, 1s and 2s improper
Tune: Algorithms

A1  1-4    End couples long cast to middle place and face original end 
           (1s facing up, 4s facing down) while middle couples meet and lead out to end places. 
    5-6    Active couples (original ends, now in middle place) wheel around halfway to face 
           middle of set (men moving backwards). 
    7-8    Active couples (in the middle) circle four to the left halfway. 
           Order is now: 2-4-1-3, 1s and 2s improper, 3s and 4s proper. 
A2   1-8   Repeat from new positions. Order is now: 4-3-2-1, top too couples proper, 
           bottom two couples improper. 
B1   1-4   Men go right shoulder around partner. (This is not a gypsy; women should stand still.) 
     5-8   End men, followed by neighbor, skip clockwise halfway around women's line to end in 
           original home place but crossed over. Dancers are with their shadow at this point, 
           not their partner. 
     9-10  In halves of the set, star right halfway. 
     11-12 Middle couples star left halfway. Men are in their progressed places but women are not. 
B2   1-4   Women go left shoulder around opposite (men should stand still). 
     5-8   Middle w omen, followed by neighbor, skip counterclockwise halfway around men' s 
           line to end opposite partner in progressed place. (Middle w omen start by dancing 
           behind their partner and around the line.) 
     9-12  Partners left-hand turn once around.
     Progression: 2-4-1-3.

Teaching hps: The progression is tricky because everyone arrives independently. Reassure dancers that this is not a mixer; partners will be reunited soon. The stars happen quickly and women must be prepared for them.

Nancy De Vore commissioned this dance as a surprise for her husband Al Blank ('a mathematician), on the occasion of his 80th birthday.
