My dad used to try to sing this. And by *try* I mean he would sing the words “O sole mio” over and over again. Those were the only words he knew, I’m sure. And by *sing*, I mean he would shout them in something almost like the tune.
When my dad was in the nursing home, my mother would ask the nurses if his constant attempts to sing drove them crazy. “Oh, no,” one nurse said. “When he’s singing, we know he’s feeling good and is happy.”
Can’t argue with that.
