I’m not sure what “MissaX.19.10.07.Vera.King.Dont.Say.A.Word.Act.1...” specifically refers to — it looks like a compound identifier that could point to one of several things (a musical/mass recording, a file name, a manuscript or archival reference, a theatrical or film cue, or a catalog entry). I’ll choose a reasonable interpretation and give a deep, structured explanation; if you meant something else, tell me and I’ll adapt.
