This occurred Sunday in New Zealand after a heavy pole that was part of the set and being moved by a performer struck her on the head during a performance of “Judas.” 

The singer left, but returned to the stage and sang an additonal 16 songs.  “I want to apologize,” she told the crowd. “I did hit my head and I think I may have a concussion but don’t you worry, I will finish the show.”
