Based on the novel “Marion’s Wall” by Jack Finney “MADDIE” was originally workshopped at the National Theatre Rehearsal Studio in 1991 after Stephen was chosen to participate in Stephen Sondheim’s Oxford Masterclass in 1990. Stephen and Shaun McKenna started work on the show in 1989 with Steven Dexter who had the idea for the show. A half-hour presentation in Oxford and later at the Lilian Baylis Studio, Sadler's Wells (at the conclusion of the Sondheim Masterclass period) proved highly successful.

The first full production opened at the Salisbury Playhouse in 1996 and got rave reviews. A year later the show transferred to the Lyric Theatre, Shaftesbury Avenue where it received excellent reviews and starred Summer Rognlie as Maddie/Jan, Graham Bickley as Nick, Lynda Baron as Mrs Van Arc and Kevin Colson as Al. Produced by Kenny Wax, directed by Martin Connor with musical supervision by Martin Lowe and musical direction and orchestrations by Caroline Humphris. Stage Door Records released the critically acclaimed 20th anniversary deluxe edition of the London cast album in 2016 with three newly recorded songs and a 12-page booklet about the show. Shaun McKenna's acclaimed book, 'Maddie and Us', chronicles the extraordinary 8-year journey Maddie took to the West End stage.

“MADDIE” concerns the ghost of a long dead flapper, Madeleine (Maddie) Marsh who was tragically killed on the way to do a screen taste for Cecil B DeMille. Maddie was on her way to becoming a huge star. Her ghost is disturbed by a young couple, Nick and Jan Cheyney who move into her old apartment in 1980’s San Francisco and uncover Maddie’s last message scrawled on the wall “Madeleine Marsh, June 1926-read it and weep!” Possessing the body of Jan, Maddie once again sets out to have the career she was denied. Along the way she causes mayhem by seducing Nick, humiliating the formidable Cordelia Van Arc at a fundraiser and utterly ruining Jan’s life. It is only when she comes face to face with her old love and former accompanist, Al Turner now an old man, that she begins to question what she’s doing. Al persuades her to leave and Maddie agrees. But then she sees a film in colour with sound...
