Sunday’s Earth Day celebration on the National Mall will feature rock group Cheap Trick. The band will perform alongside British rocker Dave Mason and Kicking Daises, a teen pop group. On the 40th anniversary of Earth Day two years ago, a concert featuring Sting brought record numbers of people in to D.C. for the celebration. This year’s show has a theme of “Mobilize the Earth.” The organization involved in the planning wants people around the world to help try to perform 1 billion green acts before Sunday. Earth Day Network president Kathleen Rogers says they have well over 900 million acts tallied already.
