On a you tube video of Jesse Lege and friends at Augusta Heritage Center's Cajun and Creole week in August of 2016 they play the Mamou Hot Step and before Jesse gives the introduction he say's something in Cajun / French that sounds like "Oh delay na mach" Can anyone translate this for me? Thank you.

It isn't French, Jesse just has a strong accent. He says "they lettin em out." Meaning people are leaving the show.

Ahh! never would of guessed it was English, I've listened to that clip many times trying to figure it out. Thanks Josh.
