I just sent out an email to everyone who has purchased musical tickets, but thought a FB post would be helpful as well. This is what the email said:
We're reaching out because our event has been postponed. The new dates are as follows. Times remain the same. Thursday May 14th @ 7:00pm Friday May 15th @ 7:00pm Saturday May 16th @ 4:00pm and 7:00pm If you were previously registered for your old date, you are now registered for your new date without having to change anything! We hope you will be able to attend our rescheduled date, but if not, refunds are available by contacting Brown Paper Tickets at firstname.lastname@example.org. Please be sure to include your order confirmation number. Thank you for your patience and support of the Northern Cass musical. We will continue monitoring and reassess the situation if need be, and will let you know if plans change. If you have any questions please contact email@example.com Thank you!
