Pourquoi me réveiller - Why awaken me, Werther - Massenet. (Non-opera buffs would probably not want to listen past the first 3 minutes of it - when the soprano clutches in. For me this is one of the outstanding tenor arias in the opera repertoire, but the rest of the opera is not up to the same standard.)
I liked one of comments to this on YouTube:
"French in opera voice with backwards German subtitles? I think the only thing I understood was "je t'aime"."
Whereof one cannot speak, thereof one must be silent.
