Just as little Savoy history, The authentic Savoy Whip that was danced by Street Swing dancers in the 1950's in Hollywood was only a five step/count move done to 4 Quarter beats. The Savoy Whip was executed with the lady being drawn into the man on the 1 &2 (3 steps) as the man completed half (180 ) turn to his right; the Whip was a two step move (1-2) where the lady stepped around to the man's right shoulder ending up in open position finishing with 3 &4 (3 steps) in an open position facing the ma having completed a 360 degree turn with eight steps taken on a total six quarter beats. The move was counted (1,2,3,) (1-2) (1,2,3) = (2 Quarter beats) (2 Q beats) (2Q beats) = total: 6 Q beats The 8 count Swingout was an innovation that appeared in the late 1980's early 1990's when Swing enjoyed a revival. The difference in the moves is that the 8 count Swingout is slower and easier to teach, but the 8 count Swingout lacks the quick snap throw out that the 6 count Whip has. To me, the 8 count Swing out is just a basic step throwing the lady out to the man's right instead of to his left. The 8 count Swingout ain't got that Swing that the 6 count Whip has. And like the Duke said, "If it ain't got that swing, then it don't mean a thing!"
