The unauthorized use of the recording of “Cum Angelis,” which begins with the lines “Procedamus in pace, in nomine Christi - amen,” led to a lawsuit and a settlement in favor of Capella Antiqua. The voice on the recitative is that of singer Sandra (“Maria Magdalena”), the wife of producer Michael Cretu.
The song was named "Sadeness (Part I)" on its single release in Germany, and "Sadness Part I" in the United Kingdom and Japan. It is a sensual track based around "questioning" the sexual desires of Marquis de Sade; hence the German release name of "Sadeness", as opposed to the English word of "Sadness" used in the UK release.
