The 88th annual Hollywood Christmas Parade rolls through Tinseltown tonight. This year’s grand marshal is “Access Hollywood” host Mario Lopez. Other celebrities expected to ride in the parade include Scott Baio, Lorenzo Lamas, former “Batman” costar Burt Ward and — of course — Santa Claus. Hollywood luminaries who served as grand marshal include Bob Hope, James Stewart and Gene Autry. The cowboy actor wrote and recorded the holiday standard “Here’s Comes Santa Claus” after riding his horse in the 1946 parade.
