Krauss had sung the bolero in the Vespri Siciliani ; and Mlle. Denise Bloch the drinking song in Lucrezia Borgia .

But the real triumph was reserved for Christine Daaé, who had begun by singing a few passages from Romeo and Juliet . It was the first time that the young artist sang in this work of Gounod, which had not been transferred to the Opera and which was revived at the Opéra Comique after it had been produced at the old Theatre Lyrique by Mme. Carvalho. Those who heard her say that her voice, in these passages, was seraphic; but this was nothing to the superhuman notes that she gave forth in the prison scene and the final trio in Faust , which she sang in the place of La Carlotta, who was ill. No one had ever heard or seen anything like it.
