The Agnus Dei credited to Georges Bizet is based on the Intermezzo from the L'Arlesienne Suite No. 2, taken from Bizet's 1872 incidental music to Alphonse Daudet's play. Bizet had only made one suite out of his L'Arlesienne music, and with the popularity of the opera Carmen running out of control in the years immediately following Bizet's death, the publisher of the by-then-departed composer commisioned Bizet's own close friend, Ernest Guirard, to compile another. Sometime after this second suite was prepared from the L'Arlesienne music, Guirard extracted the Intermezzo movement, added the Latin sacred text of the Agnus Dei to it, and published it as yet another "new" work of Bizet. The original Intermezzo begins with a snatch of Gregorian-style chant, perhaps providing Guirard with the inspiration for the setting. The fact that Georges Bizet himself had nothing to do with its creation has not deterred others for reclothing this Agnus in yet newer garb and putting it out under his name. In 1921 the Oliver Ditson company of Philadelphia issued a new version of the piece "with obbligatos arranged by Louis Ritter." A further arrangement for solo voice, chorus and orchestra, credited to Job Maarse, dates from the 1980s and has been recorded by José Carreras, Jessye Norman, and others. This piece is often heard on public radio in the United States, usually at the start of programs devoted to "music to make you relax." ~ Uncle Dave Lewis , Rovi
