Yes, we saw it on the Freedom in June. It was OUTSTANDING! Carnival's production shop really outdid themselves on it. The costumes and the props were unbelievable. I normally am bored stiff in the shows and only go because the wife enjoys them but I was entertained. They also did a salute to the Beatles, I can't remember the name of the show but it was just as good.
I can't tell you if it was a good representation of N.O. as I have never been there, but it definitely hit on the stereo types of N.O. as I know them
