Each couple, including the eliminated couples, will choose one dance from the dances they already performed.
JOOC, if memory serves I remember you said that you weren't a ballroom dancer and yet at the same time you seem to have some intimate knowledge of the show. Are you in TV production or something? (If you care to share, if not that's cool.)
The article also said that each couple will only be doing 30 seconds of the dance they had already done, which seems even weirder to me. I don't understand the point of bringing back all the couples to dance again in the first place, 30 seconds makes it even more bizarre.
I would have much preferred that the time be spent on exhibition pieces from the pros. I am just dying to see them dance with pro-partners. The demo clips at the beginning of the show are so tantilizingly short.
Internally when they cut the clip, I am going, no no wait, just a sec, that was way too fast, let me see the rest &^%* you!
It would seem a fitting finale.
