A school teacher goes viral with a video of herself telling her students not to sing during a performance of Wicked: Part One.

On Friday, November 22, teacher Ally Clements shared a video on Instagram of herself telling a group of middle school students not to sing during the movie starring Ariana Grande and Cynthia Erivo while wearing a pink wore a costume dressed as Grande’s character Glinda. The post seemed to get a lot of attention as part of a larger discussion about whether or not audiences should feel free to sing along Evil Now that the Broadway adaptation has hit theaters.

“Hey ladies, remember – this is not a sing-along,” the user, who identifies herself only as Katelyn on Instagram and is apparently based in Alabama, said in the video. “This isn’t a sing-along! I’m here to hear Cynthia and Ariana sing, not you.”

Clements’ caption to her post further suggests that she accompanied a group of students on a field trip to see her Evil when it opened in theaters. “If you see Evil with 100 middle school girls 💚🩷,” she wrote alongside the video.

“Hey, can any of you read??” One user wrote in a comment, pointing out that Clements, who posted the video, appeared to be directing her comments at students she was supervising while attending a movie theater, rather than random theatergoers . “No they can’t ❤️,” Clements replied in another comment.
