It’s finally confirmed by Guinness World Records. Edgefield Prmary School has broken the world record with 3,379 people dancing cha cha cha together on 17 July 2011 at Punggol Field. The feat was part of Punggol North’s Racial & Religious Harmony Street Parade. The entire school spent more than eight months preparing to attain a world status for this activity that it was already well-known for.
