New Orleans is an old city with a lot of traditions, one of which is the Second Line parade. In this case it was for a wedding. The parade usually goes from the ceremony to the reception, through the nearby streets. The First Line is a brass band and the happy couple, each of whom are swinging parasols. The second line is the rest of the wedding guests, walk-dancing to the music and often waving white handkerchiefs. In this case, first and second lines have arrived at the reception in the tourist-infested French Quarter and these are the final dance steps. If you’ve seen the HBO series Treme, you’ll know that a Second Line also works for funerals.
