The stage collapsed during Cheap Trick's set last night (July 17) at the Ottawa Bluesfest as the result of a sudden storm, reportedly injuring one man seriously and sending several others the hospital.

According to their official website, nobody in Cheap Trick was injured during the collapse, although a note within their statement -- "And all the best to our truck driver Sandy" -- seems to indicate one of their crew may have been among the wounded. The band's manager, Dave Frey, later confirmed to CNN that "one of our drivers will spend the night at the hospital."

On Monday morning, July 18, the Toronto Sun reported that two people had in fact been sent to the hospital, one with "traumatic injury to the addomen, pelvis and upper leg."

Cheap Trick posted two photographs of the collapsed stage on their site, as well as a picture taken just prior to the collapse, showing the band performing under ominously gray skies:

Canada's Globe and Mail reports Cheap Trick was in the middle of performing 'I Want You to Want Me' as the storm approached. A sudden strong gust of wind was responsible for the damage, according to reporter Ryan MacDonald: “People started screaming and crying. The stage was a rectangle and it had scaffolding, three, four stories high. The wind caught it and blew it backwards. It collapsed like a big tent. It was kind of unreal.”

Chickenfoot guitarist Joe Satriani, who was scheduled to perform a solo show at the festival, reported on the event via twitter, indicating that he was not hurt. Obviously, organizers shut down all stages and performances for the rest of the night, and Ontario's Ministry of Labor is investigating the accident.
