It's the first day of school at Rydell High -- or, rather, the first day of on-set rehearsals for the young stars of Fox's TV musical 'Grease: Live,' which on this dreary December day is only six weeks away, with a 7 p.m. ET air date on Sunday, Jan. 31.
It's finally back! FOX's Grease: Live airs this Sunday, January 31. Dancer Julianne Hough stars as Sandy and Les Mis actor Aaron Tveit will be Danny Zuko. Vanessa Hudgens and Carlos PenaVega join in as Rizzo and Kenickie.
