Corey Head is singing Master Moore of Moore Hall.It is his job to slay the evil Dragon and win the heart of the fair Margery in the process....thus dumping the loyal Mauxalinda in the process. Typical opera betrayals, battles, and general villainy that ends happily. And he sings the should be famous drinking song, "Zeno, Plato, Aristotle all were lovers of the bottle"
Ah, the great opera lyrics......
