Malcolm, Esmeralda is based on Victor Hugo's "<I>Notre Dame de Paris</I>" and choreographed by Jules Perrot and Marius Petipa. As for (4), do you mean Flower Festival in Genzano? It could have been literally translated from the Italian name <I>Festa dei Fiori</I>. Flower Festival in Genzano is by Bournonville, with some very lovely music by Helsted. I have seen the tambourine solo from Esmeralda, as well as the full length Flower Festival on video, danced by the Kirov.<P>I think Walpurgis Night may be from the opera Faust by Gounod as I seem to recall a ballet in the scene of the same name. Possibly someone better informed may be able to tell you more.<P>In reply to your question from the previous thread, I'm from NUS, and I'm also absolutely envious you'll be watching the Bolshoi live.
