This year’s holiday stroll in Lower Mills will include a tree lighting at 7:20 p.m. and plenty of festivities up and down the village from Milton to St. Gregory’s church. A new element this year is a ukulele singalong at the Walter Baker building, 1231 Adams St. It will be led by the Choco-leles, a group that meets each week in the common room of the old administration building which is now houses residences for artists.

Anne Ku, one of the artists in residence at the Walter Baker Building, started the weekly ukulele jam sessions last January and even offered lessons in a series of workshops. “The ukulele is a friendly instrument, light, portable, affordable, easy and quick to learn,” said Ku. “The Christmas songs we’ve chosen for the Holiday Stroll are well-known and most have few chords. It will be the first indoor caroling this season.”
