If you're a fan of "Glee" and "Archie" comics, you're going to like this: There's a four-issue "Archie" / "Glee" crossover in the works. The first one arrives this week.

"Glee" creator Ryan Murphy said the story honors and celebrates the two worlds, "Not just their similarities, but their differences, which I think we've done."

By the way, the "Glee" cast will perform their 500th song on this week's episode. It's "Shout" from the movie "Animal House". You can find the audio at EW.com.  And PerezHilton.com has audio of the rest of this week's songs.
