James studied the organ, flute and composition at the Royal College of Music in London. Together with Kit Hesketh-Harvey he won the 1987 Vivian Ellis Prize for young writers for the musical stage with his first musical Orlando.

Since then he has written extensively for the theatre, including the stage musicals Killing Rasputin (Bridewell Theatre), The Canterville Ghost (Britten Theatre), Inkle and Yarico (Edinburgh Festival, Crampton Theatre, Washington DC), Doctor Livingstone, I Presume . . . (Riverside Studios) and New Edna, The Millennial Musical (National tour and Haymarket Theatre, London) starring Dame Edna Everage and the collaborative musicals The Challenge and The Ten Commandments.

Incidental theatre music includes A Doll’s House (Salisbury Playhouse), Blue Remembered Hills (Crucible Theatre, Sheffield), The Merchant of Venice (Nottingham Playhouse) as well as songs for Kit and the Widow Lavishly Mounted (Ambassador’s Theatre) and The Fat Lady Sings.

James has composed the scores for over 100 television documentaries and dramas, - the Emmy Award winning Ten Days to D-Day (Channel 4), Adolf and Eva (ITV network) which won a Gold Badge at the New York Film Festival, In Search of the Brontes (BBC1), World War One in Colour, The Real John Betjeman, Kings and Queens, Last Train from Budapest, Great Escapes, Who Killed Marilyn?, The Search for King Midas, Britain’s Greatest Monarch, Timewatch: Exocet, The Illuminator, The Real Benito Mussolini – to name but a few, as well as the feature film Another Life, starring Ioan Gruffudd, Nick Moran and Tom Wilkinson.

In 2004 James wrote and presented the Channel 4 documentary What Made Mozart Tic?, a programme based on James’ belief that the great composer may have had Tourette’s Syndrome. This excited a good deal of interest and has been repeated a number of times.

James’ book Life, Interrupted, (Hodder/Headline) was published in April 2006 and entered the bestseller lists in its first week.

He lives in Norfolk.
