'Glee''s 500th Performance Is Tonight!

"Glee" is finally returning after a short, cliff-hanger of a hiatus, and we couldn't be happier. But that's not the only reason to celebrate tonight's episode. As star Lea Michele noted on Twitter today, "Girls (and Boys) on Film" will feature the series' 500th performance, which just so happens to be the classic "Shout."

And even better? When you download a digital copy of the single, Columbia Records and Twentieth Century Fox Television will donate 100 percent of the proceeds from U.S. sales to the music education charity Give A Note. Now that's something to sing about!

Will you be tuning into "Glee" tonight? Tell us in the comments and on Twitter!
