Derry~Londonderry organisers say that 5,400 people were involved in Saturday's bid for the Guinness World Record for the biggest choreographed song and dance routine ever staged.
They performed the 'Hard Knock Life' routine from the Annie musical in three minutes in unison to break the record.
With the current record set at 4,500 by a group in India, it means that the event at Ebrington Square had 1,000 more participants- more than enough performers to smash the record and cement Derry's place as the new title-holder.
Sandra Biddle, who helped make the biggest Annie performance happen, said the city was buzzing on the day.
"We've been meeting people saying, 'if I hear that song one more time in our home'," she laughed.
"Everyone has been practicing, and having just a bit of what we're used to up here- a bit of fun and craic."
Guinness officials will confirm the new world record within the next few weeks.
