Over the past nine years, Mamma Mia the musical has become a global sensation, grossing $2billion worldwide, and has been seen by more than 30 million people in eight languages.

We hear from theatre producer Judy Craymer, who made it all happen by taking ABBA’s music in a new direction and reinventing the songs for the stage.

There are also contributions from other members of the creative team behind the stage show, original ABBA members Benny Andersson and Bjorn Ulvaeus and stars of the film including Meryl Streep, Colin Firth and Pierce Brosnan, who reveal the story behind a major musical phenomenon.
