Pink‘s “most physically and vocally demanding” show of her life kicked off in the United States this week in dramatic fashion.

Although the crowd in Seattle gave her a warm reception, there was one element missing from the singer’s Funhouse tour: her “Sober” trapeze act. (A stand-in took over the high-flying duties during that segment.)

Pink revealed early in the program that she had somehow separated her shoulder. (She also said that her purse and phone were recently stolen.) Despite the pain, the 30-year-old refused to cancel the concert and carried on like a professional.
