High School Musical’s final performance on Friday was canceled because of a teacher shortage.

In a letter to parents on Thursday, Principal David McEachern said the show had run its course, and the school had “no other option than to cancel the performance.”

He also said that the district was “concerned about the impact the cancellation of the school musical may have on the community.”

“As a community we need this show to be safe and fun for our students,” he said.

The show’s cancellation comes just days after the cancellation and closure of the show at the prestigious Woodstock Festival in New York City, which has drawn some big names including Michael Jackson and Alicia Keys to the area.

McEachens letter did not mention the Woodstock show.
