So why did the CBC spend 3/4s of the 90s talking about her?

So today I learned Nana Mouskouri is not Canadian, has nothing to do with Canada, she's not a Greek Canadian from Montreal or Danforth of whatever.

Bonus Nana Mouskouri trivia: If you run up to her and punch her repeatedly in the head she won't do a thing about it. This seems way more therapeutic than just repeating that "when she sings, mice scurry" gag.
