I have always loved the plaintive carol I Wonder As I Wander written by folklorist John Jacob Niles. The melody and lyrics were inspired by hearing a young Appalachian child sing a fragment of a long-lost song, and whenever I hear it I imagine someone wandering out in the night across the worn, snowy Appalachian hills. This version comes from the beautiful album titled Christmas Star: Carols For The Christmas Season by the Cambridge Singers, a wonderful album to add to your Christmas collection.
