Dr. John has announced that he will have to cancel his appearances at Brooklyn’s Nolafunk Mardi Gras Ball tonight and tomorrow, February 6, due to an illness. According to his Twitter, Dr. John will try to make up the shows at a later date.

The two-night run was slated for The Hall at MP, and the venue has announced that the 10th Annual Mardi Gras Ball will go on as a free event, and ticket buyers will receive a refund.

The weekend event will feature a New Orleans menu by the adjoining restaurant MP Taverna, plus performances by Davell Crawford and New Orleans’ Soul Brass Band.
