We already know that "Glee" will be covering a lot of music from Michael Jackson's library, but they will also cover the Bee Gees in an April episode. Creator Ryan Murphy is working with Barry Gibb, which will revolve around the Bee Gee's "Saturday Night Fever" soundtrack.

We may also see John Travolta guest star in this episode if he agrees to it. Cory Monteith is friends with Travolta and Murphy hopes this will help get him on the show. I would love to see John Travolta dance and sing on the episode so hopefully he will agree to it.
