Even Ebenezer Scrooge would be convinced to embrace the holiday spirit during Woodstock’s Wassail Weekend, a three-day celebration of the season. The revelry starts with a bang when the Latin-jazz trio La Voz de Tres (pictured) take center stage at Woodstock Town Hall Theatre. On Saturday, merrymakers tour the area’s historic homes, where they encounter encyclopedic docents, musical performances and plenty of old New England charm. Concluding the festivities is a rousing choral rendition of Handel’s Messiah in the picturesque Our Lady of the Snows Catholic Church. Warm up your vocal cords — audience members are encouraged to lift their voices in the spirit of good cheer. Humbuggery, be gone!
