This wonderful musical was first presented in 2005 at the lakeside Walensee Festival in Walenstadt, Switzerland. The show played a series of highly successful performances and was also produced at the State Theater in Dessau, Germany. Due to the enormous success of “Heidi 1″ the authors were commissioned to write a total of three different productions of the musical. “Heidi 2″ opened in Walenstadt in 2007 and also played in 2008.

The current production is the ultimate and enhanced version of the play. New scenes and wonderful songs have been written by the authors Shaun McKenna and Stephen Keeling. The new score is beautifully arranged by the Swiss orchestrator Stefan Mens.

The ‘ultimate’ HEIDI has just celebrated a very successful workshop in London. A new workshop will be presented in London by early 2015, after which first licensed productions will be presented.


When Johanna Spyri’s young son falls ill, all she can do to comfort him is tell him stories.  The story he most wants to hear, and helps to invent, is that of Heidi, the small Swiss girl who touches the lives of all around her – Peter the goat boy, her grumpy Grandfather and the villagers in the Alpine Dörfli.  When Heidi is whisked away to new adventures in Frankfurt with the wealthy but crippled Klara and the tyrannical Fräulein Rottenmeier, neither she nor Johanna is prepared for the dramatic twists her story will take.  Heidi is a fresh, funny, heartwarming family musical, a sparkling new version of a much loved classic tale.

All songs composed by Stephen Keeling with lyrics by Shaun McKenna

Stephen Keeling – MUSIC

Born in Staffordshire, England, Stephen trained at Goldsmith’s College, University of London, gaining an honours degree in music. He was chosen by Sir Cameron Mackintosh to study with Stephen Sondheim during Sondheim’s tenure at Oxford University as the Visiting Professor of Contemporary Theatre. Subsequently Stephen composed the music for Maddie (book and lyrics by regular partner Shaun McKenna with Steven Dexter), which was workshopped at the Royal National Theatre Studio before receiving its first full production at the Salisbury Playhouse. The production then transferred to the Lyric Theatre, London produced by Kenny Wax. The London Cast Recording has recently been released on iTunes.

He was the co-composer, along with Laurence O’Keefe, for La Cava (book by Dana Broccoli, lyrics by Shaun McKenna and John Claflin), which transferred from the Churchill Theatre, Bromley to the Victoria Palace Theatre, London later moving to the Piccadilly Theatre.

In 2003 Stephen and Shaun McKenna were commissioned by John Havu and Walter Hitz to write a celebrated musical adaptation of Heidi (based on an idea by Stef Mens).

Heidi opened in Switzerland at an open air arena, Lake Walenstadt 2005 to universal critical acclaim. A new production opened at the Anhaltisches Theater Dessau, Germany 2006.

In 2007 and 2008 a sequel, Johanna and Heidi, played in Switzerland and was nominated for the prestigious Prix Walo award. This was followed by a prequel The One True Thing.

Stephen and Shaun McKenna have also written a musical sequel to Peter Pan, The Return Of Peter Pan (creative development by John Havu and orchestrations by Stef Mens) represented by the Pegasus Agency, Berlin .

Stephen has also composed the music for My Father’s Son, a musical set in nineteenth century Sheffield and based loosely on Shakespeare’s Hamlet (book and lyrics by award winning writer Stephen Clark performed at the Crucible Theatre, Sheffield and the Lilian Baylis Theatre, Sadler’s Wells). Stephen has also written the music for a musical adaptation of The Amazing Mr Blunden (book and lyrics by Martin Guerre lyricist Edward Hardy) performed at London’s Theatre Museum, Covent Garden.

With the noted author Jonathan Miles he has written several musicals including Dietrich and the Red Spy and Children of Paradise set around the filming of Les Enfants du Paradis.

For children he has written The Last Wave (with the writer Peter Spafford), a musical based loosely on the events of the Children’s Crusade.

Stephen also composes choral music and music for media. He has recently composed a Requiem.


Stefan Mens is a Swiss musician who grew up in a mostly classical oriented family. He began to play the violin at the age of 5, switched to the guitar when he was 13, studied jazz and always shared a big love for rock music.

Because of this wide background in musical knowledge he became a stilistically very versatile musician – be it as player on the guitar or as a composer/orchestrator.

Stefan has worked mainly in the area of musical theater. He wrote a few shows which were produced in Switzerland and Germany.

Stefan Mens created the original concept for the Heidi Musicals. Besides the orchestrations and the conducting of the HEIDI – The Musical World Premiere he was the orchestrator of HEIDI 2, “Tell – the musical”, “Alperose”– a musical with the songs by Polo Hofer

Stefan is a regular writer for orchestras/bands in Switzerland (including work for Swiss National Television).

​He played in the orchestra of the European productions of  “Cats”, “Les Misérables”, “Jesus Christ Superstar” and “Evita”.
