I loved them, too. They were really great! I hope they're not hurt by Shavar's edit in the finals.
Before them (07) was "new disco" (AKA Lady GaGa-style disco) with Jesse and Julia. They were interesting, but I'm not a Lady Gaga fan. The judges seemed to like it, but I sensed that they were overly pushing it because of the "new genre" factor.
Jesse = from Ontario, contemporary
Julia = ballroom dancer from Alberta(?) -- when she became pregnant, she was told she wouldn't be able to dance professionally (and her son is adorable!)
