Like the song, they literally roast chestnuts on an open fire and share them with people passing by.
It all started more than 20 years ago when Printers Row resident Pat Rafferty was listening to the song "Chestnuts Roasting on an Open fire", according to organizer Sam Clark.
"He heard the song and wondered if anyone had ever eaten chestnuts" said Clark.
Rafferty died of cancer in 2003, so neighbors decided to continue his tradition in his honor.
This year, they prepped, roasted and passed out more than 20 pounds of chestnuts.
