Sounds like more than one person has come up with a great idea
independently. I always thought that it was Nick Hawes who first
wrote a dance with intersecting contras with a square (or squares) at
the intersection(s).
I had a phone conversation with him probably in the early 90s. His
memory of what he had called (at Ashoken I think) was:
A circle left 4 steps, balance, California twirl, pass through
B allemande left corner (neighbor) and swing partner.
C ladies chain over and back
He couldn't remember the other 16 beat phrase and told me to just pad
out the rest to come up with 64 beats.
I called the above to a crooked tune and the ever creative Becky Hill
took the choreography and added do-si-dos with neigbor and partners
to pad it out.
If any one is in contact with Nick it would be interesting to get
more information.
