I'm 49 and have known about Chita Rivera from before the time I saw Kiss of the Spider Woman, some 20 years ago now.
But then again, I'm a theater fan, and have been a fan for a long time. Because of that, over the years, I have been interested in not only shows that have come into existence during my lifetime, but also those that have come before. Hence my being here, my love for theater, and my passion for revivals. Even older, more dated ones like On the Town.
As for The Visit, I hope it has a healthy run. I thought it was great. Different, but great.
I can see how it might not appeal to everyone though, and it might not necessarily appeal to the tourist who is in town for a few days and find themselves gravitating to the bigger shows. I was really glad I saw it though.
