The hit musical Mamma Mia! opened in London's West End in 1999. Using the songs of the Swedish pop group ABBA, the stage show was followed in July 2008 by Mamma Mia! the movie and ten years later by a sequel, both of which have broken musical box-office records. Louise Hidalgo has been talking to Mamma Mia's creator Judy Craymer about how it all began.
