An attempt to break a record for simultaneous dancing will take place this afternoon at 8.30 eastern time when Michael Jackson fans around the world ape his moves from the video for “Thriller.” It is expected dancers in the US, Australia, Germany, Russia, and Pakistan will all take part in the attempt. In a similar event last year, 4,179 people in 52 cities simultaneously performed the six-minute dance routine, according to Montreal’s Gazette.
