This is just a footnote in followup to Jane's comment dated 26 May 2013: In the spring of 1993 I met with the late Vera Krasovskaia, one of the most prolific and revered Soviet/Russian ballet critics and historians, at her cottage at Komarova outside of St. Petersburg. I had gone to see her about my research on the ballet librettos of Aleksei Remizov, but somehow the conversation turned toward Oklahoma where I live. I was greatly surprised that someone as well-read as Krasovskaia did not know Agnes Demille, had never heard about DeMille dream ballet from Oklahoma, nor read Dance to the Piper or And Promenade Home (although Krasovskaia read and spoke English). Then again, not so surprising. The iron curtain was not just a military or political phenomenon, but even more essentially an information barrier.
