Do shows ever get cancelled or postponed due to inclement weather?

Never heard of a cancellation.

No!

I have never heard of an cancellations.

Nevered heard of one being cancelled.

I went to a show last year during a storm, wasn't a bad one but "The show must go on"

I don't think I have ever heard of any cancellations.

Only if its a show for a school during a school day. They have postponed those before.
