UPDATE on Sunday, September 2 at 1:30 p.m. PT: Bono offered a health update on U2's website, saying "I've seen a great doctor and with his care I'll be back to full voice for the rest of the tour. So happy and relieved that anything serious has been ruled out. My relief is tempered by the knowledge that the Berlin audience were so inconvenienced. There was an amazing atmosphere in the house, it was going to be one of those unforgettable nights but not for this reason… We can't wait to get back there on November 13th."
U2 cut short an Experience & Innocence 2018 tour concert in Berlin on Saturday after Bono lost his voice onstage.
The 58-year-old frontman had performed a few songs over the course of 20 minutes and was heard struggling to sing "Red Flag Day." He and the band then stopped the music so he could address the audience. He speculated that stage smoke in the Mercedes-Benz Arena had affected his voice.
"I can promise you I have not been smoking," he told the crowd, as seen in videos fans posted online. "But this is like a giant cigar. I've lost my voice and I don't know what to do...it was singing like a bird about 10 minutes ago."
