A high school in Missouri stages the musical “Grease.” But the high school gets complaints, writers “complaining that scenes of drinking, smoking and a couple kissing went too far, and glorified conduct that the community tries to discourage. One letter, from someone who had not seen the show but only heard about it, criticized “immoral behavior veiled behind the excuse of acting out a play.” The school superintendent “watched a video of the play, ultimately agreeing that ‘Grease’ was unsuitable for the high school, despite his having approved it beforehand, without looking at the script. Hoping to avoid similar complaints in the future, he decided to ban the scheduled spring play, ‘The Crucible’ by Arthur Miller.”
