Andrews is performing on Mardi Gras, but he won?t be in his hometown New Orleans _ he?ll be at the White House. Andrews and his Orleans Avenue band are joining B.B. King, Buddy Guy, Keb Mo, Mick Jagger and others slated to perform Tuesday for President Barack Obama and first lady Michelle Obama at a black history month event. By Stacey Plaisance.
