Geeezzz, nobody's talking about the Byrds......the originators of what we call "Folk-Rock"??? Their version of "Old Blue" is fabulous. And how about "You Don't Miss Your Water". "Turn, Turn, Turn", of course.....yeah, Pete wrote it, but its credentials are sure folky. There are a few others of theirs, too. The Band's version of "Long Black Veil" is superb- although it's not traditional, it's surely in the folk song bag. BTW, I take exception to the identification of "How Can a Poor Man Stand Such Times and Live" by Ry Cooder as a rock'n'roll version. NOT R&R....definitely folk-style (Ry at his best).
