Cheerwine, the “legendary soft drink of the South,” and indie-rockers The Avett Brothers will host a charity concert Oct. 19 to support Operation Homefront, Big Brothers Big Sisters and the University of Virginia Children’s Hospital. The Legendary Giveback Concert, which will take place at the nTelos Wireless Pavilion in Portsmouth, Va., also will be streamed online for anyone who pledges to volunteer in their communities. Fans can pledge online or on Facebook to donate their time to a local charity or community organization in exchange for a special code to access the online event. The town that pledges the most volunteer hours also will earn the chance to host a Cheerwine-sponsored Legendary Giveback concert viewing party in their hometown on the night of the big event.
