Producers then announced the Wednesday evening and Thursday matinee were off but have now confirmed the entire rest of the run has been cancelled.

Posting on social media, Panka said she was "very sad that the situation is happening right now".
"People are saying and doing things that I completely don't agree with, and it's very scary to be here right now, especially as a person of colour - but just I'm worried for everyone in our company," she said.
"There were fires in the street. The company that I work for and the theatre have decided to cancel yesterday's show, which was good."
Paul ColtasThe Mean Girls musical comedy is based on the hit 2004 filmPanka said she had received angry messages from fans about the cancellation of the shows and she asked that people consider how she is feeling at the moment.
"I just wanted to address something because especially, for me, as a person of colour, and people are actively targeting black people.
"I just really wanna ask people to think before they send me a DM because I haven't left my house because I am scared to do so.
"My blinds, I just opened them slightly to make this video, but they have been closed."
Panka said this was not a case of an actor being ill but it was a safety issue.
"I'm just very careful because I'm not even from this country," she said.
"It's not our choice to not come in. It's a safety issue. And it's not just for us, it's for the audience and it's for everyone who works at the theatre too."
