The Sudbury Celebrates 375 Committee, which is spearheading preparations for the town’s 375th anniversary observances next year, is inviting schools and religious institutions, arts and cultural groups, artists, historians, and businesses to initiate or create events, programs, and exhibits connected to the community and its history. The events may be held any time next year except for Sept. 4-6, which is the official celebration weekend. Activities can include community sings, period costume balls, theatrical performances, sporting events, fashion shows, educational programs, or town beautification projects. Those interested should e-mail the committee at email@example.com. For more information about the anniversary celebration, visit www.sudbury.ma.us. Full story for BostonGlobe.com subscribers.
