I'm sorry to get back to you so late Helene! I didn't see any casting online but now that I have the program I can tell you (sorry again for not seeing this earlier, I was away from a computer etc for a few days.) :
June 13th:
Prince Siegfried: Leonid Sarafanov ; Odette/Odile: Oksana Bondareva; Pas de trois: Ekaterina Krasyuk, Viktor Lebedev and Valeria Zapasnikova; Jester: Denis Tolmachov; Big swans: Valeria Zapasnikova, Irina Kosheleva, Astkhik Ogannesian. Cygnets: Ekaterina Khomenko, Anna Kuligina, Veronika Ignatyeva and Marina Nikolayeva.
That was the performance I saw and it was really really wonderful, and after getting to meet Leonid Sarafanov backstage afterwards I can say he is a very kind person... really good English as well. It was a truly heavenly experience for me as he is my favourite dancer! Oksana Bondareva will dance Odette/Odile for every evening performance (13th, 14th, 15th and 16th) and Irina Kosheleva will dance O/O for the June 16th matinee. Viktor Lebedev also performed Prince Siegfried on June 14th, June 15th and June 16th matinee with Sarafanov only dancing again on June 16th evening.
