Fans of Glee are already familiar with the great music produced each week on this show.

But a much bigger audience will soon be introduced to the cast, as various actors and actresses from the show will perform the national anthem prior to game 3 of the World Series later this month.

The game is scheduled for October 31 and will take place in either Los Angeles or Philadelphia, depending on the winner of the National League Championship Series.
