Now in its second season, the TV show "Glee" has struck a chord with audiences in the United States and elsewhere. The story revolves around the members of a high school student chorale group, known as ‘New Directions’. Every episode features the actors performing popular songs with complex choreography. Many U.S. schools have similar vocal groups. VOA’s Susan Logue visited one in Chantilly, Virginia, that is celebrating its 25th anniversary.
