Not to scoop Brad Wilber (if such a thing were possible!) but La Cieca has just heard that the much-discussed opening night of the Met’s 2012-13 season has been settled. Starring in a new Bartlett Sher production of L’elisir d’amore will be Anna Netrebko, Matthew Polenzani and Mariusz Kwiecien, with Dulcamara and conductor TBA.
