Millennium Square in Leeds was transformed into a boogie wonderland as 300 dancing schoolchildren tried to smash a world record.
Youngsters from 12 Leeds primary schools performed an Olympic-themed routine for cheering crowds as part of the Big Dance 2012 School Pledge.
More than 200 schools in Yorkshire and 500,000 people across the globe also joined in at various venues to break the Guinness World Record for the Largest Simultaneous Dance Routine.
The Netherlands currently hold the title, with 1,472 locations and 264,188 people.
Kippax Greenfield School pupil Libby Hall, 11, was one of the children chosen to dance at Millennium Square.
She said: “I was amazed by how many people were here and the effort that everyone put into it.”
Sharp Lane Primary School pupil Colette Frearson, seven, said: “I am never going to forget this day ever. It was so much fun.”
Classmate Mae Pizzey said: “I enjoyed everything about it.
“I like dancing and go to ballet but I was still nervous.”
Anna Walker, teacher at Sharp Lane Primary in Middleton, said: “The children were very excited when we told them they were going to dance at Millennium Square.
“They said that all their dreams had come true.
“It’s great because they get the experience of doing something together with other schools and get a bit of excitement and a buzz.”
Tracy Witney, head of education and community programmes at Northern School of Contemporary Dance in Leeds, lead the routine.
She said: “We’ve taught the dance in Leeds schools for the past few months.
“It went brilliantly. The children had the routine down and seeing the determination on their faces was really sweet.”
Other schools at Millennium Square were Mount St Mary High School, Little London Primary, Blenheim Primary, Middleton St Mary’s, Deighton Gates Primary, Templenewsam Halton Primary, East Garforth Primary, Whitecote Primary, Tranmere Primary and Sharp Lane Primary.
