Another good resource is the children’s album by Pete Seegar. My children adore it and so do my husband and I. Elizabeth Mitchell is another artist I so enjoy and she covers many folk songs. Keep on the sunny side, This land is your land, You are my sunshine, Lavenders blue, Down by the riverside, Follow the drinking gourd, The farmer in the dell, Micheal row the boat ashore, Big rock candy mountain (clean version), Home on the range, and We shall overcome are some we like, plus so many more. I like singing nursery rhymes in song form for the littlest ones.
