The cast of Fox's new hit show "Glee" sang the National Anthem before Game 3 of the World Series Saturday night in Philadelphia.

Amber Riley, who plays Mercedes Jones on the show, sang lead vocals while the rest of New Directions group sang backup. No mash-ups, no dancing.

"Glee" is pre-empted for a while due to World Series games on Fox, and will return November 11.
