John Stewart, director of vocal activities, will direct the concert, which features Washington University Vocal Ensembles and organist William Partridge Jr.

The program includes the Bridal Chorus from Richard Wagner's Lohengrin; the Anvil Chorus from Giuseppe Verdi's Il Trovatore; the Humming Chorus from Giacomo Puccini's Madame Butterfly; Dona nobis pacem from Bach's B-minor Mass; and Hallelujah from Beethoven's Christ on the Mount of Olives.

"This sing-along is purely for fun," Stewart said. "How often does one get to sing the Bridal Chorus from Lohengrin in English translation of the German? And I'm out searching for an anvil to use for Verdi's Anvil Chorus."

Those who wish to may sit in special sections arranged according to voice type (soprano, alto, tenor, baritone), though those who choose not to sing are also welcome to attend. Copies of the music will be available.
