Fans can register now for a pre-sale for day two tickets to When We Were Young 2023, set to begin on Friday at 2 p.m. PT.

Festival organizers originally announced the 2023 WWY lineup last October before the first gathering even occurred. The festival ultimately sold out three straight days of the same lineup, however, when it finally came time for WWWY to debut on October 22nd, 30–40 mph winds blew through Las Vegas, forcing organizers to cancel day one. With the next two days of the festival already sold out, the only thing organizers could do for the fans who traveled from all over the world was issue refunds. The following two days of the festival went off smoothly, with My Chemical Romance donning elderly prosthetics to drive home their legacy as emo forefathers.
