[Callers] Does this dance already exist?

Wrote this one on my way back from calling Norfolk. Slow M'Ocean Becket A1 Pass thru to an Ocean Wave (Ps are facing in opposite directions). Balance forward and back. Swing your SHADOW (who is facing you in the next wave). (Gents, make the ladies come to you.) End facing across. A2 Pass thru to an Ocean Wave. Balance F/B -- swing your Partner, who is facing you in the next wave. End facing your original Ns. B1 Ladies chain to your N. Ladies allemande R 1.5 (continue to hold Rt hands) B2 Ladies pick up your partner, star promenade across with a butterfly whirl (to the lady's side). Promenade across (to gent's side), with ladies passing RIGHT shoulders, and curl RIGHT to face the next neighbor, ready to pass the Ocean. I can't think of another dance that starts this way -- anybody? April Blum
