Hatfield Flash Mob
Dozens of young dancers have taken over the Galleria shopping centre in Hatfield with a massive Flash Mob event.
The unexpected show, by the Living The Dream Performance Company, took place yesterday (Wednesday) - they're planning to do another one with even more dancers at St Pancras International Station in London on New Year's Eve.
Both events are raising money for the Teenage Cancer Trust.
Zoe Jackson - the founder of Living the Dream - said:
"Young people of today are tomorrow's leaders. They bring energy, new perspectives and a new voice to our society but sadly, they are often misrepresented in the media. Living The Dream shows young people at their very best, thus is a positive representation of today's youth in the media to counter negative images of young people."
