It was pretty much a given that J.K. Rowling’s appearance at Lincoln Center on October 16 (her only public event in the U.S. to promote The Casual Vacancy, her first novel for adults, published by Little, Brown) would be a tough ticket. But the situation became a bit tense for fans when an unauthorized link to purchase tickets to the event online went live on Sunday night, Sept. 9, some 12 hours before the official on-sale time. Not surprisingly, the program, which was at first planned for an audience of roughly 1,200, quickly sold out on Monday morning.

After some initial confusion and panic, Jazz at Lincoln Center issued statements on Monday and Tuesday acknowledging the glitch and announcing that all purchased tickets, including those bought Sunday night, would be honored. The event has been relocated to a larger venue—the David H. Koch Theater at Lincoln Center—to accommodate the larger crowd. Those who purchased tickets online Sunday night are being contacted by Jazz at Lincoln Center “to process tickets for the event at the new location.”

Below is the most recent statement from Jazz at Lincoln Center:

On Sunday, September 9, Jazz at Lincoln Center’s ticketing system was breached and an unauthorized link to purchase tickets to the J.K. Rowling The Casual Vacancy event on October 16 was distributed online. This breach did not result in the breach of purchasers’ personal information. In order to accommodate customers who purchased tickets on September 9 as well as customers who purchased tickets on September 10, Jazz at Lincoln Center has secured the David H. Koch Theater at 20 Lincoln Center as the new location for the event. Each customer who purchased tickets prior to the official on-sale date and time will be contacted directly by Jazz at Lincoln Center to process tickets for the event at the new location. The event remains sold out. At this time, only customers who purchased tickets on September 9 and 10 will be accommodated. Although neither Little, Brown and Company nor J.K. Rowling are responsible for this situation they were keen to make sure that no person who legitimately bought a ticket was left disappointed, and are delighted this matter has been resolved in this way and apologize for any confusion that may have been caused in the meantime. Jazz at Lincoln Center apologizes too for any inconvenience and looks forward to welcoming everyone to the David H. Koch Theater on October 16.
