Kevin Costner and his band were due to take the stage at the Big Valley Jamboree in Canada yesterday when a storm touched down causing the stage to collapse. One person died and at least 60 people were injured.
Costner was okay, but we're told two members of his band were taken to the hospital. A witness on scene tells TMZ he saw Costner helping people out of the wreckage.
Country music singer Billy Currington was performing his last song when the stage collapsed. He was ok.
In a statement to TMZ, Costner's rep said: "We are so saddened by the loss of life and injury that occurred on a day that carried so much promise, but turned so wicked so quickly. We hope to return to Alberta in the future to help with the healing."
