In 2008 I wrote this dance using a diagonal chain
Elizabethan Gypsy Becket
A1 Gents Allemand Left 1 1/2, Neighbor Swing
A2 Promenade across, Ladies Chain, on Right Diagonal to Shadow
B1 Hey (Ladies X Right Shoulder)
B2 Partner Gypsy and Swing
Inspired by (might even be considered a variation of ) Chrysalis by Don Flaherty
Cheers, Bill
