The members of Cheap Trick escaped serious injury, but a member of their entourage was hospitalized after the stage at the Cisco Ottawa Bluesfest collapsed Sunday night.

Marc Messier, a spokesman for Ottawa Fire Services, told the Associated Press that a 49-year-old man was in serious condition with abdominal, pelvic and leg injuries. Another had a spinal injury and a third person experienced chest pains. At least eight other people were treated at the scene for minor issues including twisted ankles and anxiety.

According to a statement on the band’s website: “Severe weather hit the stage as Cheap Trick was performing at the Ottawa Bluesfest tonight. The stage blew down and collapsed. Everyone is shaken up but band and crew are all fine. Cheap Trick hopes that everyone who attended the show is also ok. Robin says ‘Fortunately the band and crew are all lucky to be alive and we’ll see you down the road. And all the best to our truck driver Sandy.’ ”

The band’s manager, Dave Frey, later told CNN that “one of our drivers will spend the night in the hospital, and though we’re not sure how, Cheap Trick are grateful and happy to say that everyone, including all the concert goers, are okay.” Watch a fan-recorded clip of the collapse below.
