Mardi Gras has come to Philadelphia. And Mayor Nutter and his first lady will help kick it off at noon tomorrow, in a prelude to the 7th annual West Oak Lane Jazz & Arts Festival. Along the 7200 to 7400 blocks of Ogontz Avenue, the King and Queen will lead a New Orleans-favored, Mardi Gras-styled parade featuring the sounds of Royal Brass Band, and the Kimmel Center Youth Ensemble. State Rep. Dwight Evans will serve as Grand Marshal, and present the mayor with a key to the neighborhood. This year’s mega jazz fest, with more than two dozen acts, artists and food, runs from Friday, June 19 through Sunday, June 20. Check here for more information, and for road closures, which start today.
