It’s a “Glee” Christmas special — live! The Gleek Guy Squad, Matthew Morrison, Chris Colfer and Cory Monteith, talk to ET about their on-set charity event to help disadvantaged kids.As part of their collaboration with the American Express Members Project, they hosted about 60 local school children, who got to visit the set and interact with the cast as part of the Education Through Music program. Cast members helped those in attendance make their own musical instruments using household objects to make home-made tambourines, egg shakers, jingle bells and more.The Education Through Music program was then presented with a check for $100,000 to help them continue their good work.Source
