DENVER (AP) — The Colorado Symphony says a series of marijuana-themed fundraising concerts will be invitation-only in an attempt to address concerns that audiences were going to break the law by smoking weed in public.

In a statement Tuesday, the symphony also said it was removing information about the three events scheduled to start later this month from its website and refunding tickets purchased already. The events at a Denver art gallery will now be open to a list of VIP guests by invitation.
