The lights on the tree, located on the mall in front of town hall, were turned on during a ceremony Thursday night.

BRAINTREE - The season’s biggest celebrity rolled in on a fire truck and was immediately mobbed by his biggest fans.

Mayor Joseph Sullivan made a request.

“Santa, will you help us light our Christmas tree?” the mayor asked.

And with a little help from Jaice and Jaya Arsenault, the children of Public Works Director James Arsenault, Santa flipped the switch to illuminate the tree as the crowd shouted “Merry Christmas.”

Afterwards, Sullivan led the crowd in a sing along of “Rudolph, the Red-Nosed Reindeer.”

The Thursday night ceremony on the town hall mall attracted a crowd of families who snacked on hot chocolate and gingerbread cookies from Montilio’s.

Sullivan ask the crowd to take the community spirit shown at the tree lighting and “carry it through into the new year.”

This year display at town hall is the largest in recent years, with lights strung on the columns of the building and around the adjacent former Thayer Public Library building. Banners with holiday greetings are hung on utility poles along Washington Street.

The mayor thanked the staff of the town’s Department of Public Works for putting up the lights, and said he hopes to have lights all along the mall next year.

The event was sponsored by Quincy Credit Union.
