I have to admit, I've seen most of the classics in theatrical form as well when they come to Toronto, I also enjoyed The Jersey Boys right on Broadway in Manhattan, but I still love watching them on TV.
I'm 48 years old and have probably watched The Sound of Music 40 times. Every year at Christmas we just had to watch it and now I enjoy watching it with my own kids.
On wednesday we're going to see the production of Chicago. I don't know the story, but always look forward to seeing a show!
