Wales: Buddy ends on alarming note.
About 620 people were told to leave Llandudno's Venue Cymru on Monday night when the fire alarm went off.
Six firefighters from Llandudno arrived the theatre at around 10.30pm.
It turned out to be a faulty fire alarm on the ground floor.
Dave Gillum, a 57-year-old painter and decorator from Penmaenmawr, who had watched the show with wife Kate, said: "We were starting to leave the theatre when an announcement came over on the tannoy for the general public and staff to evacuate the building.
"It wasn't suggested it was a fire or any life-threatening situation."
A Venue Cymru spokeswoman said: "We would like to apologise for any inconvenience caused by the alarm."
Buddy: The Buddy Holly Story continues at Venue Cymru until this Saturday, August 26, with shows each night at 8pm, plus 2pm matinees today and Saturday. For more information call the theatre box office on 01492 872000 or visit
