NEW YORK (Reuters) – A COVID-19 outbreak within Disney’s stage show “Aladdin” prompted an 11th-hour cancellation of Wednesday evening’s performance, one night after the production joined the return of Broadway’s biggest musicals from a pandemic-induced hiatus.

Producers posted a Twitter notice (NYSE:) just before curtain raise to say that testing protocols detected an unknown number of “breakthrough” infections in the company’s “Aladdin”, at The New York Amsterdam Theatre.

It stated, “Because our guests, cast and crew are top priorities, tonight’s performance is canceled, Wednesday September 29th,” and that refunds would be made at customers’ points of purchase.

According to the tweet, “Aladdin”‘s future performances would be announced Thursday. The animated Disney film was based upon Disney’s 1992 hit cartoon.

After 18 months of unprecedented closure of New York City’s theaters, a number of Broadway’s most popular shows such as “Hamilton”, “The Lion King,” and “Wicked,” were reopened mid-September. The “Aladdin”, a new addition to the drama, had only joined on Tuesday.

Producers and theater labor unions have established health safety guidelines that require cast members and crew to show proof of immunization or an exemption to be able to perform on Broadway. They also need to test for coronavirus each three days.

Masks must be worn by stagehands and members of the public during performances.

On Sunday, the 74th Annual Tony Awards was held. It was skipped in 2020 because of the shutdown.

The New York Times reports Wednesday’s cancellation was confirmed by the New York Times as the only confirmation for an open Broadway production after June’s “Springsteen on Broadway”.
