Singers from the San Francisco Opera performed the “Opera A La Carte” production of Donizetti’s “The Elixer of Love” during the morning assembly Nov. 12, at Bullis Charter School. Sixth-grade students took small speaking roles, for which a field trip to the War Memorial Opera House to observe a dress rehearsal of the romantic comedy helped them prepare. Jennifer Ashworth, a professional singer from the San Francisco Opera Guild sang the role of Adina, supported by the heroine’s friends, (from left) Sophie Stanley, Emily Garverick, Olivia Hon and Anne Goodman. Brian Thorsett of the guild sang the role of Nemorino, the shy hero of the opera who buys a love potion from the traveling snake-oil salesman Dr. Dulcamara, the guild’s Michael Taylor. Michael Touchi at the piano took the place of the orchestra. Sixth-graders Carl Elson, Lindsey Raven and John Hersey played the parts of Sergeant Belcore, a soldier and Hercules, respectively. School staff members Jeron Carr, Becky Sorrentino and Joe Williams comprised the rest of the platoon. The absorbing performance was followed by a question-and-answer session.
