I saw this one, too! We waited in line at the half-price ticket office and got a pretty good deal on "upper-crust" tickets. There is a lot going on the floor, in the air, and on the tiered stages all the time, so be prepared for a mindful. It's a very different Cirque show in that respect--there isn't one act that captures your entire attention, it's full blown movement all the time.
I was one of the naive folks who was a fan of the Beatles and just didn't know it. I kept jabbing my husband and saying "The Beatles wrote that one, too?" It was an enjoyable, energetic night out. Be prepared for some serious munchies afterward!!
