Fred’s Lounge in Mamou, Louisiana, is a dancing and drinking destination… on Saturday mornings only. That’s the only time it’s open. For years, Saturdays have featured live traditional Cajun music, a live radio show, a devoted community of Cajun dancers, and visitors from around the region—and the world. What started as a local dive has become internationally famous. By nine a.m., middle-aged couples waltz a wide arc around the band, as 83-year-old proprietor Tante Sue takes healthy swigs from a bottle of cinnamon-flavored schnapps while squeezing her chest in time to the music as if playing an accordion. How does Fred’s maintain this mix of locals and outsiders? We sent reporter Eve Troeh out on a Saturday morning to drink a few beers (or Bloody Mary’s) and find out.
