Hi Quickstep,
Your ballroom history may not have included the passing of Maxwell. It was wrote: On Saturday, 3rd October, 1964, the dancing world lost one of its greatest characters with the death at Bognor Regis of William Joseph Maxwell Stewart, aged 68. He left a widow and two sons, Joseph and Julian. The figure, Double Reverse Spin, was originally called, a Reverse Spin. All spins are open turns and students to the profession became confused because of the gent closing the feet on the Toe Pivot, but because there is no weight change it was still classed as an Open Turn. The name Double was added at a later stage for a reason I can't give just now. Maybe in the future if someone is interested. Would you please answer phil.samways' query. I'm also curious.
