I've seen two traveling Cirque shows. I agree that they are great entertainment and that seeing one of the televised shows is no comparison.
The first show I saw was Varekai in Chicago. I was blown away. The acrobatics and stunts were awesome. There were humorous parts too. It was very entertaining in many ways. I also saw Quidam in Cincinnati. This was good but not as good as the first show.
The music at the two shows I saw was original stuff, and for lack of a better word, maybe a little to "artsy" for my taste. I can imagine that a Beatles show would be awesome.
