The day after Thanksgiving a crowd of more than 25,000 Portlanders will unite in a joyful sing-a-long led by Thomas Lauderdale, members of Pink Martini and a diverse array of our city’s talented musicians and chorale singers. The evening’s program will feature Mayor Wheeler, city dignitaries and Santa Claus as they ‘flip the switch’ to illuminate 14,000 colorful lights on our city’s centerpiece to the holiday season- the spectacular 75′ Douglas-fir generously provided by Stimson Lumber Company.
