Alanis Morissette's Jagged Little Pill is now a jukebox musical. But how has this achingly personal collection of songs been transformed into a show about an American family coming apart at the seams? We ask the show's Oscar and Tony-winning writer, Diablo Cody.

Also, we meet Toby Marlow and Lucy Moss who wrote Six the Musical for the Edinburgh Fringe as students and have since opened the show on Broadway and the West End and won a Tony Award.
