In this Friday, Oct. 25, 2013 photo, spectators wait for the premiere of the opera ''Cinderella'' by Gioachino Rossini at the Greek National Opera in Athens. The Opera has managed to transform itself from a loss-maker to an income-generator with a new fan base. Three years ago, the Greek National Opera had an accumulated debt of 17 million euros and was producing a deficit. By simply streamlining the organization, reducing the operating cost and coming to settlements with creditors and suppliers, artistic director Myron Michailidis managed to reduce the debt to 4.7 million euros. The opera has taken its performances outside the walls of its historic theater in central Athens and settled in unexpected venues, including the metro station at Syntagma Square and the port of Piraeus.
