I was royally entertained last night by the Opera singers of the Guildhall School of Music and Drama. I saw their performances of two very strange operas: L'heure Espagnole by Ravel, and Les Mamelles de Tiresias by Poulenc. Some great music, but both were extremely odd. I think that was the idea, though. The second one was based on a surrealist play by Appollonaire. It involved a man becoming a woman and producing 4o,ooo babies on his own during a brief entracte. Then everybody danced around the stage waving a handbag.
Opera is quite a strange thing. If it didn't exist, you wouldn't invent it.
