A Utah school that invited Glasses Malone to perform at the prom took the invite back, calling the rapper’s lyrics “inappropriate” for the setting.

Malone was scheduled to perform at the Clearfield High School senior prom last night—until administrators learned a little more about the content of his music. The performance would have been sponsored by a local radio station, U92.

The contest invited students to text the station for an opportunity to win a performance by a popular band or artist. According to a report by the Standard Examiner Davis, students from Clearfield sent more than 10,000 text messages to U92.

“By far, they blew the other schools out,U92’s promotions coordinator, Sergio Sanchez told the publication.

Clearfield’s principal, John Mills said his administration did not find out about Malone until Monday. After learning of his lyrics, he made the decision to rescind Malone’s invitation. “The type of songs he does is not appropriate for our school functions,” Mills said.

When an assistant principal attempted to look up Malone’s lyrics on the schools computer, but was unable to do so because of filters, Mills says “that gave some indication of what to expect.”

Sanchez told the paper that he felt “bad for the school and the kids,” but empathized with Clearfield’s administration.

“I definitely understand the concern because Utah’s mentality is so conservative,” he said.
