Most of mine have already been mentioned, but I'm going to stick in a bid for Robbie's foxtrot (with the umbrella) as well

Holly and Artem's black and white classical swan thing

Holly and Artem's dance the week Artem was injured

Holly and Artem's pink dress thing (rumba I think)

Holly and Artem's long red slit dress dance this week

Robbie and Olla's wembly dance

Olla pretty much all dances and ditto Holly.

Harry's quickstep this week and pretty much all his dances.

Actually, could we just have Holly with anyone, Robbie&Olla and Harry with anyone dancing please? Vincent and Flavia doing an Argentine Tango every week and Anton doing a ballroom every week with Natalie. And Christina dancing with Katya doing a musical type dance each week with any partners. That'd be worth the license fee.
