Katharine McPhee will no longer be performing at the St. George Theatre in Staten Island, NY on March 30 for its annual Red Carpet Gala and Benefit Concert.

A press release states that the reason for the cancellation is due to a scheduling conflict with Waitress in London. In Katharine’s place, R&B group The O-Jays will be providing the entertainment for the evening.

Per the press release, for patrons who purchased Katharine McPhee concert tickets only, refunds will be available at the original point of purchase, via Ticketmaster or the St. George Theatre box office.
