The show will go on. Just at a later, as-yet unspecified date.
Green Day's show at the Fillmore Auditorium in San Francisco on Sept. 28 has been postponed following lead singer Billie Joe Armstrong's check-in to rehab, according to reports.
Armstrong was on-stage with Green Day at the iHeartRadio Music Festival in Las Vegas on Friday when he was given a one-minute cue to cut the music and get off stage. That enraged the guitarist and singer, who was reportedly in the middle of his band's set.
"One minute left, one minute (expletive) left. You're gonna give me (expletive) one minute? ... I'm not (expletive) Justin Bieber, you (expletive)," he said, according to reports, before smashing his guitar and stomping off of stage.
Green Day's set was being cut short for Usher, according to reports.
Armstrong, 40, was also hospitalized in Italy a few weeks ago during the band's tour there. He was suffering from dehydration, according to reports.
No makeup date for the Sept. 28 show has been announced, but concert promoter LiveNation said that tickets will be honored for a future show.
Green Day won't be performing in San Diego but does have a show scheduled Dec. 4 in Santa Cruz.
