The “Glee” Cast’s “Thriller” / Yeah Yeah Yeahs Mash-Up Has Leaked

The "Glee" cast will perform a mash-up of MICHAEL JACKSON'S "Thriller" and a YEAH YEAH YEAHS song called "Heads Will Roll" on Sunday's post-Super Bowl episode.  And you can get a taste of it now, because the audio has leaked online.

 --According to Billboard.com, the episode will also feature new "Glee" versions of Katy Perry's "California Gurls", Lady Antebellum's "Need You Now" and "Bills, Bills, Bills" by Destiny's Child.

 --By the way, Britain's not-so-reliable "News of the World" tabloid reported that MADONNA was thinking about touring with the cast of "Glee" . . . but Madonna's rep says that's NOT true.
