The Eagles will be supporting Don Henley and his Walden Woods Project at a show on September 16th at the Citi Wang Theatre in Boston.

The show will raise funds for the charity, which aims to protect the Walden Woods, a forested area in Concord, Massachusetts made famous in writer Henry David Thoreau’s book Walden. The night also includes a special guest, actor Robert Redford, who will receive the organization’s 2014 Global Environmental Leadership Award in “recognition of his enduring commitment to a range of environmental initiatives.”

Don Henley, who founded the Walden Woods Project, will present the award. He says, “Bob Redford was an environmentalist long before the well-being of our natural resources became an international concern. Throughout his extraordinary career as an acclaimed actor, director and producer, he has devoted himself to myriad environmental initiatives too lengthy to enumerate. Redford has stated, ‘I think the environment should be put in the category of our national security. Defense of our resources is just as important as defense abroad. Otherwise what is there to defend?’ I can’t agree more.”

The Eagles resume their History of the Eagles tour on August 25th in Tacoma, Washington.
