U2's show last night in Berlin, Germany came to an abrupt end in the middle of their set when frontman Bono suffered a sudden "complete loss of voice." While an official cause of his voice-loss has yet to be revealed, Ultimate Classic Rock points out that Bono had commented on the fact that smoking was allowed in some parts of the venue they were in and he was feeling the effects.

"This is like being in a giant cigar," he said. "I’ve lost my voice and I don’t know what to do. I was singing like a bird about 10 minutes ago. I don’t know what to do. I’m sure it will pass.”

The band then began playing "Beautiful Day," but it was obvious that the singer's condition was worsening. He eventually stopped the music and apologized to the crowd, saying they would take a "break," but the band never returned to the stage.

The three remaining members of the band released a statement on U2's website early this morning (Sept. 2):

We're so sorry for tonight's cancellation.  Bono was in great form and great voice prior to the show and we were all looking forward to the second night in Berlin, but after a few songs, he suffered a complete loss of voice.

We don't know what has happened and we're taking medical advice.

As always, we appreciate our audience's understanding and all our fans' support in Berlin and those who travelled from afar. We will update you very soon.

Adam, Larry and Edge
