In analogy to the BCS superconducting condensate, these coupled dancers came together when the music started and continued in a fluid motion next to each other without bumping into each other or stepping on each others toes; however for the "multiple dancers" analogy to apply to the actual BCS condensate, the partners in a given couple would be executing their flawless movements while very far apart, separated by the members of many other couples, a coordinated dance more easily imagined than implemented.
