Beverley Knight among guests at Charlie and the Chocolate Factory's first birthday party

Charlie and the Chocolate Factory opened at the Theatre Royal, Drury Lane on May 26 2013 and yesterday celebrated it's first year at the venue with a special gala performance.

The show, adapted from Roald Dahl's classic children's story, currently stars Alex Jennings in the role of Willy Wonka.
