Fox’s Grease Live is airing on Jan. 31 — the day after the SAG Awards, which are on a Saturday, which… I have thoughts — and these are several of your Rydell High students. (Aaron Tveit is Danny Zuko.) The cast that’s the most important, though, is the one I just read: BOYZ II MEN will be playing the Teen Angels that sing “Beauty School Dropout” to Frenchy. Can’t we just have them pop up at important parts of the production and sing refrains from their other hits? “I’ll Make Love To You” will be needed basically every 30 seconds.
