People across London are in last minute rehearsals for the finale of a week-long dance festival.
Londoners have taken to the event, organisers said
One of the main features of the Big Dance is an attempt to set a world record for the largest number of people dancing one routine for two-minutes.
Londoners on the Millennium Bridge from 1230 BST will be among dancers in 37 cities across England taking part.
Jacqueline Rose, one of the organisers from the mayor's office, said Londoners have really taken to the event.
"Dance is a great art form and so many people do it," she said. "It cuts across cultures, there isn't the language issues and it's great fun.
"One of the things that's been brilliant about Big Dance is we've been able to celebrate the incredible range and diversity of dance styles that we have in London."
