When I first heard their "Brown Eyed Women" I assumed it was traditional, or at least an older Country song, maybe 1930s.

Their compositions don't always mesh perfectly with the "trad" ones, but they don't clash, either. "Jack-a-roe" comes from a Child ballad, considered "trad" but "Babe, It Ain't No Lie"is an original by Libby Cotton, "Standing On The Corner" by Jimmie Rodgers, "Louis Collins" by John Hurt. "It Hurts me Too" should be credited to Tampa Red (1930s or '40s), but I think they credit Elmore James for his re-write.
