‘Glee’ episode spoilers: Mercedes’ ‘Disco Inferno’ shown in new video

She’s got a solo…

Now that “Glee” is going to be airing new episodes pretty much non-stop until the end of the season, that means one fantastic thing for all fans of the show — the opportunity to not have to wait to get any more behind-the-scenes clips.

For Tuesday night’s new episode “Saturday Night Glee-ver,” there is now video proof below that we are going to see Mercedes belt out a rendition of “Disco Inferno.” Unfortunately, we are really just limited to hearing a few snippets of the song while Jane Lynch explains what exactly makes the disco era so cool. (There’s also a bonus cameo in here from Jenna Ushkowitz, who does her best impression of what “cool dancing” should be.)

Unfortunately, there is still a great deal about this episode greatly shrouded in mystery, whether it be just what the story for this overall episode is or how Alex Newell of “The Glee Project” is going to fit in to the picture as Wade — a student who ends up spending some time with Kurt in the episode.

The one thing we know for sure after watching this new clip? The more footage we have of Amber Riley singing, the happier we are ultimately going to be.
