Loved the I DO, I DO story, DR ChasSmith! I also have one from 1967: Mom took me for my first visit to NYC and we saw CABARET. We waited at the stage door afterwards and it was right next to the I DO, I DO stage door. We saw Robert Preston and Mary Martin come out and get into a limo together. When I close my eyes, I can still see them waving out the back window of the car.
