Someone, quite rightly, has questioned whether I meant to use the word "subtitles" in "Relocation to Murder" when describing the English translation that is put up when you watch an Opera in its original language. Well, I never knew it had so many other names - here is what Wikipedia has to say on the subject.
"Surtitles, also known as supertitles, SurCaps, OpTrans, are translated or transcribed lyrics/dialogue projected above a stage or displayed on a screen, commonly used in opera, theatre or other musical performances. The word "surtitle" comes from the French language "sur", meaning "over" or "on", and the English language word "title", formed in a similar way to the related subtitle. The word Surtitle is a trademark of the Canadian Opera Company."
