Nanny McPhee the ballet

It's London's only ballet company to be made up entirely of children. And it's one of the toughest to get into. More than six hundred auditioned for just sixty places in the London Children's ballet.

The company, now celebrating it's twentieth year, decided to put on a special performance of Nanny McPhee. The ballet is based on the 2005 film starring Emma Thompson, who goes to live with a family with seven naughty children.

Emma North went along to one of their final rehearsals.
