Fortunately, the incident occurred at midnight and no one was hurt. Only security personnel were on site, so no staff from contractor Serious Stages, which supplied the equipment, were present.
"It really was a case of the show having to go on," said show production manager Keith Morris. "We had a national TV deadline to make and it goes without saying how impressed I was with Serious Stages - the company really pulled it off."
The 70mph gusting winds destroyed the fully constructed stage, including its lights. The wind also caused serious damage to a large mature oak tree.
Serious Stages' team, led by Steven Corfield, worked through the night to create a replacement roof.
The PA and video rigging was also fitted the next day as originally planned.
As soon as the site was cleared a second Serious Stages team, led by Vic McConnell, built a new, two-bay Orbit roof, finished and fully skinned the day before the concert.
Morris and his team ensured that all Health and Safety procedures were followed, while lighting contractor HSL supplied technicians to disentangle its damaged equipment and provided replacement fixtures and trussing.
A total of 10,000 people attended the concert at Eirias Park in Colwyn Bay to see performances that included Ronan Keating and The Feeling.
