Real life sisters, Lauretta and Sharon Gavin have lived together for thirty years. This year Lauretta is getting married and for the first time in their lives they will be living apart. The sisters take us on an hilarious journey of real life stories, sketches and anecdotes as they look back on growing up together in their new show 'It's a Long Road That Doesn't Have a Bend.' This is the London preview before they take the show up to Edinburgh.
