Before Kendrick Lamar takes the field on Feb. 9, the letter notes that "past vulgar performances" might have been okay in those cities, but not in the Big Easy.

Kendrick Lamar is due to headline this year's Super Bowl half-time show next month. But ahead of the event, a group of Republicans and campaigners in Louisiana have complained about previous performances by artists including Rihanna and Jennifer Lopez.

The 37-year-old rapper has been tapped to headline this year’s NFL championship halftime show, where he will be joined by his longtime collaborator and R&B star SZA. And while many might (understandably) assume Lamar would be getting a hefty paycheck for his service, that couldn’t be further from the truth.
