The Copper Family is a multi-generational British folksinging family whose work spans the period from the 1840s to the present. They sing traditional folk songs of south England and are the only and original source for many of the songs they sing. Their style of delivery is rough-and-ready unison and harmony, mostly a cappella, and their subject matter is farming, the seasons, and the country life in general. Their Wikipedia site (http://en.wikipedia.org/wiki/Copper_family) and their official site (http://www.thecopperfamily.com/) give more details.
