Organizers say the March 23rd fundraiser will take place in a Fenway Park pavilion in Boston.
Proceeds will go toward programming at EverWonder Children's Museum, an effort started in 2011 to establish a children's museum to Newtown.
Organizers say late Sandy Hook Elementary School Principal Dawn Hochsprung, who died in the shooting, was one of the earliest supporters of museum plans.
The museum will operate in a recently donated temporary space while officials raise money for a permanent location.
Future plans for museum exhibits include a tribute to the shooting victims.
