Celebrate the most wonderful time of the year in style at the annual Holiday Pops concerts at Symphony Hall. Since 1973, the Boston Pops orchestra has shared its love of the season with its legion of followers by performing an array of seasonal tunes, and even engaging in some audience participation with its traditional sing-a-longs. Conductor Keith Lockhart once again leads the way, joined by none other than Santa himself. Speaking of which, special kids matinees take place at 11 a.m. on Saturdays and Sundays, featuring treats for the little ones sitting up front and even post-show photos with the jolly one from the North Pole, who is taking time out of his busy yuletide schedule to put smiles on the faces of Boston’s tiniest music fans.
