I remember the dark-skinned guy with glasses with that very nice baritone voice. He was singing the songs live while the other members of the circus family were dancing. All the girls were so flexible, especially the lady that performed balancing acts on two metal rods. She's pretty too and she reminds me of Idina Menzel.
There were also illusions that were performed and I was still amazed with their performance even if I know that those were just tricks (they really move fast that everything felt real). Those were really some of the acts that I looked forward to.
