This is a concept call that combines the Random, Twosome, and Solid (e.g. In Tandem, As Couples, and Siamese) concepts. It works with 4-dancer calls that have definite separate parts.

Definition: Dancers do the first part of the call in the appropriate solid formation, then alternate between twosome and solid for the remainder.

Reverse Dynamic Duo - Starts as twosomes and alternates with solid.
