DAVENPORT, Iowa -- The show must go on -- even if it means sacrificing your cell phone's battery.

Davenport North High School was performing during the Mt. Pleasant Music InMotion Invitational in Iowa on Saturday when the lights went out. A few seconds after the outage, a few audience members turned on their cell phone flashlights and used them as spotlights.

The power outage lasted three minutes.

Northside Establishment is the varsity show choir and consists of a 48 member vocal ensemble comprised of students in grades 9-12.
