Nonsense Room Productions has come a long way from putting on small-scale Edinburgh Fringe performances of Hairy Maclary. The company now has a global reach with tours of Asia and Australia on its CV, and is proud to be back in the Scottish capital to play a major part in this year's Edinburgh's Christmas celebrations.

In the Spiegeltent just off Lothian Road, Nonsense Room will put on a show that's never the same twice across the festive period. Based on the hugely successful book by writer Pippa Goodhart and author-illustrator Nick Sharratt, You Choose is an interactive musical production that creates a unique story every time through a series of challenges and games.

'The audience will experience the usual ingredients of our previous shows such as Hairy Maclary or Shark in the Park,' explains Nonsense Room's musical director, Matthew Brown. 'So there's a colourful set design, friendly characters, catchy songs and a real sense of fun. But the twist for this production, is that it culminates in a final scene where elements such as location, costume, characters, pets and friends are determined by audience choices.'

Also, through a series of game-show style sections, one half of the audience will compete against the other to choose the location and vote for their favourite act in a spoof talent competition. After the success of Shark in the Park, this is Nonsense Room's second venture into the books of Nick Sharratt. What is it about his stories that appeals to kids as well as to the company?

'Nick's work is instantly recognisable and his artistic style has an element of theatricality that enables the transition from page to stage to be particularly effective,' says Brown. 'We had a great experience working together previously, with Nick coming up with the set design for Shark in the Park, and we're thrilled to be repeating the process for You Choose.'
