The Met Helps You Keep Track of Who's Doing What With Whom

From a cast change advisory for upcoming performances of Rigoletto:

Two rising young sopranos will make their Met debuts earlier than originally scheduled when they share the role of Gilda in Verdi’s Rigoletto later this fall, replacing Aleksandra Kurzak, who has withdrawn due to pregnancy. Russian soprano Irina Lungu will sing the role on November 11, 15, and 18, and Bulgarian soprano Sonya Yoncheva will sing the role on November 21, 27, 30, December 4, and at the December 7 matinee.  Kurzak is expecting a baby this winter with her partner, tenor Roberto Alagna.
