Armstrong took to Instagram last night to share the news that due to a “very serious family emergency” with one of the band members, they were forced to cancel last night's show in Santa Ana and the remaining West Coast shows.

The band will be coming back to finish out those postponed dates, but there is no further word one when those rescheduled shows will take place. 

“To everyone. One of our band members @longshot is dealing with a very serious family emergency. It’s with heavy hearts we need to announce tonight’s show in Santa Ana and the rest of the west coast shows will be postponed. We love you all and we will be back. Please send good vibes to each other. All my love, Billie Joe.”
