Don Pasquale - San Francisco Opera.

A young student, Ernesto, who lives with his old bachelor uncle, Don Pasquale, has refused to wed the woman of his uncle’s choosing because he is in love with a young widow, Norina. Pasquale has decided to punish Ernesto by getting married and fathering an heir, thereby cutting off his nephew without a penny. Dr. Malatesta, a friend of Pasquale as well as Ernesto and Norina, has devised a plan to both save Pasquale from his folly and help the young couple.
