Paul Simon's zydeco-flavored song That Was Your Mother starts like this:
A long time ago, yeah
Before you was born dude
When I was still single
And life was great ...
At least these are the lyrics that I find online.
The use of "dude" strikes me as unlikely, incongruous, and sort of funny. Anyway, I don't hear "dude", I hear "doo". It seems to fit the song better if that phrase is a Cajun term of endearment. Is there such a term in the Cajun dialect?
