From splits to stilts: Dancers learn circus skills

Dancers at Northern Ballet have been taking lessons in circus skills, including juggling and stilt-walking, for their production of Cinderella.
The production includes a scene described as "a traditional Russian Christmas market", involving slightly less balletic street entertainers.
Colin Paterson went to rehearsals to find out how the dancers were taking to the new physical challenge.
