We also take this opportunity to add a little update to the list we reported: Borderline and Open Your Heart are actually mixed into one song as sort of a medley while all the other songs are performed in full or in an edit version. All songs' arrangements are inspired by the album original versions of the songs except forExpress Yourself, inspired by the famous "Video Version" and Crazy For You which is presented as an exclusive acoustic guitar version.

And now here's the article that appears on Playbill.com:

Entertainment Weekly’s Oct. 30 cover story on “Glee” had a clutch of tantalizing scoops about the second half of the hit dramedy’s inaugural season, one of which was that Madonna had granted the TV show permission to use her song catalog for an all-Madge episode.

Now, the first trickle of information about that upcoming show has arrived: Theexhaustively detailed Madonna fansite MadonnaTribe is reporting a list of songs that will be featured. The complete list, which leans heavily toward classic 80’s/’90s-era Madonna, comprises “Borderline,” “Open Your Heart,” “Burning Up,” “4 Minutes,” “Crazy for You,” “Like a Virgin,” “Like a Prayer,” “What It Feels Like For a Girl,” “Vogue” and “Express Yourself.”

Despite the professional sheen of MadonnaTribe.com, we’re going to take the song list with a grain of salt, primarily because the ten titles being tipped are double the number of songs usually presented in an episode. So unless the all-Madonna show is through-sung or will include one very big medley (not a bad idea!), we’re speculating that this is just an extended list of songs the “Glee” producers are seeking to clear from rights-holders. Given the length of time it can take to clear song rights, an extended song list would offer the show’s creatives enough options to choose from when the show eventually goes into production.

But hey, if we’re wrong and “Glee” producers manage to shoehorn ten Madonna songs into 42 minutes, we won’t complain.

“Glee,” which stars Broadway’s Matthew Morrison and Lea Michele, returns to FOX with fresh episodes April 13.
