Question: Who adapted the book into a musical, which features music by the man who also wrote music for "Cabaret" and "Chicago?"
Context: Ippolito Fiorini (c. 1549–1621) was a composer and lutenist, and the "maestro di capella" at the court of Alfonso II d'Este in Ferrara during its entire existence (1568–1597).  As "maestro di capella" his role was largely an administrative one, however in addition to being involved with the music of the chapel he also was involved with the "concerto delle donne."  He also played the archlute.  He wrote music for the duchesses' "balletti" to the text of Giovanni Battista Guarini, although none is extant, and probably also wrote for the "concerto delle donne".  He was in charge of the "Accademia della Morte" in Ferrara from 1594 to 1597. Étienne Moulinié (10 October 1599 – 1676) was a French Baroque composer.  He was born in Languedoc, and when he was a child he sang at the Narbonne Cathedral.  Through the influence of his brother Antoine (died 1655), Moulinié gained an appointment at court, as the director of music for Gaston d'Orléans, the younger brother of the king.  For this post he wrote sacred and secular music, for voice or voices and lute or continuo.  He also wrote music to accompany the "ballet" or other dances.  He taught Gaston's daughter, Mlle de Montpensier.  Moulinié worked for Gaston until the latter's death in 1660, at which point he was forced to find new employment.  For this he returned to his birthplace of Languedoc.
