D1:  1s cross right shoulder, go outside and below the 3s, meet on the line,
     set (2s set at the same time, 3s stand there); meet and lead back to 
     the center (improper) while 2s turn single.

D2:  1s cross, go outside and above the 2s, meet on the line, set while
     the 3s set, lead back to the center (proper) while 3s turn single.
============================================================================
Some notes: 
This dance is thoroughly symmetrical.
The A part is the same figure as the A of "The Bishop".
All movements have cues in the music.
The D part can be viewed either as a giant figure 8 from above, or as the 1s 
doing a cross, cast, and lead up (complicated by setting).
The dance is really unforgiving, but every figure ends with the 1s in the
middle proper, so if it falls apart just go back there.
It's really cool when it works.
