The Concert Choir of Washington University, under the direction of John Stewart, director of vocal activities in the Department of Music in Arts & Sciences, performs the national anthem before the Dec. 5 NFC battle between the St. Louis Rams and the San Francisco 49ers at the Edward Jones Dome. The 80-some members of the choir, which will also be in concert at 8 p.m. tonight in Graham Chapel, remained to watch the game from the sidelines. The Rams won, 16-6.
