The clappers: Palmas (clapping) are a crucial part of the show. I honestly do not know how the three men were able to produce such consistent sounding claps in harmony with each other for over an hour. Their hands must get tired!
The tourists: There was a man sitting on the front row with his iPad propped on the stage. He literally filmed the entire show. Even the dancers were laughing at him. If you're reading this: don't be that guy.
The male dancer: Though he was an amazing dancer, his fly was down during the entire 30 minute solo. Call me childish, but it almost appeared intentional when he would take dramatically long strides, emphasizing the issue.
The guitarists: I have never seen such impressive guitar playing. These guys played from the heart - alone on the stage on a wooden stool without sheet music. At one point I even counted the fingers on one of the guitarists - I was certain he had an extra in there to help him make those sounds!
