On Monday (September 13), pop favorites Mumford and Sons made good on its promise to perform at Mardi Gras World. The show was initially scheduled for June 13 but scrapped when bassist Ted Dwane underwent surgery to remove a blood clot from the surface of his brain. At Mardi Gras World, an appearance by the Preservation Hall Jazz Band during Mumford and Sons’ encore made the much-anticipated, long-awaited night a little more memorable for the fans faithful.
