Around 6,000 Michael Jackson fans in Los Angeles and more around the world attempted to break the world record for having the most people simultaneously dance to Thriller.
The so-called Thrill the World dance-a-thon was organised by various Jackson fan clubs in Los Angeles, New York, Washington DC and other places worldwide on October 25, 2009.
The current record was set by 13,597 people in Mexico City, on what would have been Jackson's 51st birthday.
Performers included children, teachers, and university students. They came dressed in body paint, blood-spattered wedding dresses, prison garb, and as ghouls.
The global event was ostensibly launched in Vancouver, but started at the same place around the world, according to a clock on a conference call by organizers.
The dance party in Buenos Aires brought together adults, teenagers and children, who were not even born when Thriller first hit the record stores.
In France, some 60 people aged from 11 to 73 signed up to take part in the Thriller dance extravaganza in the western village of Gourin.
