I saw Robert and Elizabeth in a gorgeous production at Paper Mill in either the late 70s or early 80s. I had always loved the score and was anxious to see it. As I recall—and it was a long time ago—it was old fashioned even then and seemed to be firmly planted in operetta territory. I don’t know if that production was intended as a Broadway tryout, but if it were, it was also clear why it didn’t transfer. A pity as the score and production were beautiful.
