In July 2018, John Sullivan's son, Jim Sullivan, announced that an "Only Fools and Horses" musical was nearing completion, with a script by Jim Sullivan and Paul Whitehouse. Jim Sullivan said, "Back in 2010 my Dad had been toying with the possibility of a stage show but sadly didn’t get the chance to commit to it. In 2015 we met with the producer, Phil McIntyre, and agreed to develop the idea. Soon after that, Paul Whitehouse came on board and things have been bubbling away ever since. I am very pleased and excited to say that the show will be launching early next year." The musical launched on 9 February 2019 at the Theatre Royal Haymarket, London.
