Singing on a lark?
Couldn’t be. She was so good. She sang O Sole Mio, popular in France with my grandparents. I remember my great grandmother (MY great-grandmother, born in 1879), singing that song at family dinners.
O Sole Mio is very popular in North Korea, where the latest thing is the Beatles.
A year later I went back to that restaurant. The girls were no longer singing and couldn’t remember ever having done that before.
One more hmm moment
