We had Sundowners with a group of dock neighbors last night.  Lots of talk of the Carnival. Of course that song came up.  Titles ranged from 'Soggy Day' to 'Sorry Day' to 'Soliday' (?).  Our friend Mike, from the catamaran Zero to Cruzin, finally stepped in and cleared up the mystery for me.  He said it's 'So We Dey', meaning loosely 'so we're good' or 'Que Sera, Que Sera' as another friend Carrie put it. This morning I looked it up on YouTube (what would we do without YouTube??)  and had to share.  To get the most out of it, make sure your speakers are on full blast and be sure to play it over and over for at least 2 days.
