Mystic Seaport Museum’s annual Lantern Light Tours turn 40 this year, and the anniversary of this progressive play brings something new to the proceedings while making references to the past.

The production, which runs from Nov. 23 through Dec. 22, features a script titled “A Christmas Sea-Chantey: In prose being A Story of 1876 Greenmanville” by Rebecca Bayreuther-Donohue, who has been part of the Mystic Seaport Museum staff for years and has participated in Lantern Light Tours for two decades.

The storyline pulls from that ever-popular holiday tale, Charles Dickens’ “A Christmas Carol,” and brings back characters from previous Lantern Light Tours.

“As this year marks our 40th Lantern Light Tours production, the script has some call-backs to previous shows for a touch of nostalgia for those who have been coming for years,” says Nathan Rumney, the museum’s supervisor of interpretation, theater and music.
