History
In 1990 composer and lyricist Stephen Sondheim took the Cameron Mackintosh chair in musical theatre at the University of Oxford, and in this capacity ran workshops with promising writers of musicals, including George Stiles, Anthony Drewe, Andrew Peggie, Paul James, and Stephen Keeling. These writers jointly set up the Mercury Workshop in 1992, which eventually merged with the New Musicals Alliance to become Mercury Musical Developments.
