TBH I hadn't been too impressed with the pro dances this series until seeing Vincent & Flavia's Midnight Tango showcase last week and the 60s/Grease pro dance at Wembley. It was great to see it filmed live and almost came over as well on the TV (watching it back last night).
I also loved the Hollywood ballroom showcase last year that Vincent, Flavia, Brendan, Natalie and Anton and Erin did with their girls in pale pink dresses (and the champagne bottles).
One of my all time favourite ones though is Anton and Flavia (Let's Face the Music) fusion with Vincent and Erin joining in/partner swapping etc.
