Romance, glittering ballgowns, dizzying waltzes, and abundant quantities of champagne feature in this semi-staged performance of operetta highlights from France and its Pyrenean neighbour, Spain. Led by Charlie Morgan and Ricardo Gosalbo, Guildhall School singers and pianists surrender to the irresistible melodies of Jacques Offenbach, Charles Lecocq, André Messager, Manuel Fernándex Caballero, and Pablo Sorozábal.
