The finishing touches are being put on the courtyard at the Jacksonville Landing in preparation for the 30th annual Christmas tree lighting ceremony at Downtown’s riverfront mall. Arthur Crofton from The Morning Show on 96.1 WEJZ-FM will host the lineup of musical performances that begin at 6 p.m. Friday. The program will be capped by illuminating the 78,000 lights on the 56-foot tree and fireworks above the St. Johns River. For those who can’t attend, the ceremony will be streamed live at firstcoastnews.com.
