Bon Iver and Moses Sumney covered Sade’s “By Your Side” at Bonnaroo

Last weekend was the seventeenth annual Bonnaroo festival in Manchester, TN. Bon Iver took the stage for not one but two unique sets, the second of which took place late at night and featured a number of special guests. Moses Sumney was one of them, and he joined Vernon on stage for a predictably soul-melting cover of Sade's Lovers Rock standard "By Your Side." Watch the performance for yourself, below.
