Dance of the Day - Smooth
Paul and Barbara appear to be trying to brand themselves - they've really put up a lot of their videos. That said, they're pretty amazing. There waltz is beautiful, if a bit pretentious, and their tango choreography is a bit too waltz-like for my taste, but their foxtrot and Viennese are perfect.
