I rather doubt that the vast majority of the American populace has hear of Jussi Bjorling. And the ONLY reason that I know of him and have heard recordings of him, is that I come from a long line of opera lovers, who talked about "THE GREATS" and even debated about who was better than the others. And they also knew a few opera stars, whom I also knew as a kid and as a young adult; not to mention the fact that my parents lived in the same apartment building as Renata Tibaldi and errily, you could hear her practicing in their guest bathroom, through the air vent. Not a pleasant thing at all; quite discomfiting actually!
Maybe jussie is a childhood name for Justin.
