Although she often sang individual arias, opera was not Ferrier's natural forte; she had not enjoyed singing the title role in a concert version of Bizet's Carmen at Stourbridge in March 1944, and generally avoided similar engagements.
A pesar de que frecuentemente cantaba arias individuais, a ópera non era o forte natural de Ferrier; non desfrutara cantando o papel principal nunha versión de concerto da ópera Carmen de Bizet en Stourbridge en marzo de 1944, e xeralmente evitaba compromisos similares.
