In another photo, Santana and Rachel pull off a duet in the choir room, while Brittany sings in front of a grand piano. Additionally, there is an image featuring Blaine, who looks sleek in a black suit, in what seems to be another musical number from the "Dance With Somebody" episode.
A week before honoring the late "I Will Always Love You" hitmaker, "Glee" will play tribute to John Travolta's 1977 dance flick "Saturday Night Fever". Titled "Saturday Night Glee-ver", the April 17 outing will also mark the debut appearance of "The Glee Project" season 1 finalist Alex Newell, who portrays a mystery man named Wade.
Wade has been described as "the love child of Kurt and Mercedes and will turn to them for much advice." Newell recently spilled that he will share many scenes with Jonathan Groff, hinting that Jesse St. James' return will come in no time.
In another news, "Glee" has been renewed for a fourth season by FOX. Other shows recently picked up for a new season by the network were "New Girl" and "Raising Hope". The former will return for its sophomore season, while the latter will be back for its third season.
