Unfortunately, that pre-game show was advertised as Cirque du Soleil. I knew immediately who was and who wasn't part of Cirque du Soleil. I've seen two of their shows, and all I have to say is if you get a chance, go see one. It is unbelievable and unforgettable! The acrobatics from the swings were the only ones from their show.
The dancers, all bands, singers, "cheerleaders," were NOT part of them.
I suffered through a Cirque du Soleil show once. Some of the most amazing acrobatics I've ever seen, also one of the most boring presentations I've ever seen. It was really incredible how they could show such amazing stuff and make it so mindnumbingly dull.
