The saints may still go marching in at Mardi Gras – but instead of parading down Bourbon Street, it may be on the famed Las Vegas Strip. “We plan to formally approach (Mayor) Ray Nagin about hosting Mardi Gras and turning it into a giant philanthropic event benefiting Hurricane Katrina victims”, Vegas power broker David Chesnoff (Britney Spears’ lawyer!) told Hot Stuff September 11. Hard Rock Hotel & Casino comedian Jeff Beacher (the best man at Nicky Hilton’s 2004 Sin City wedding) is rounding up the talent, and Ceasars Palace headliners Celine Dion and Elton John tell Hot Stuff they’re also supportetive of the relief effort. Spears could also be among the performers if Mardi Gras goes to Las Vegas next February.
