New Orleans’ annual Mardi Gras celebration will once again have an LSU flare, as the LSU Tiger Marching Band, Golden Girls and Colorguard will perform as part of the 131st annual parade for Rex, King of Carnival, according to a news release.

With a theme of “Lore of the Ancient Americas,” the 27 floats of the 2012 annual Rex parade will roll at 10 a.m. on Tuesday, through the streets of uptown New Orleans. The Rex procession travels the traditional uptown parade route, beginning at the intersection of Napoleon and South Claiborne Avenues and traveling down St. Charles Avenue, through Lee Circle and looping around on Canal Street, weather permitting.

“The Golden Band from Tigerland” last participated in the Rex parade in 2008. This year, it will precede the new permanent “Butterfly King” float, the fifth float in the parade.

“The LSU Tiger Band is honored to represent Louisiana State University in New Orleans, across the state and on the world stage as part the 2012 Mardi Gras season,” said Roy King, director of athletic bands at LSU.
