Grant Stott hosts a one-off special to celebrate the 20th anniversary of River City. At the show’s iconic set in Dumbarton, Grant is joined by current cast members and familiar faces from the past to celebrate the soap’s history and showcase the results of a public vote that invites fans to select their favourite storylines. And there are performances from superfan Susan Boyle and Tall Ship landlady Caitlin McLean - aka actor and performer Gayle Telfer Stevens.
