The Brothers Four recorded this in the sixties on their "In Person" album. Their sound is rather mellow and not very "folky" but I like it nonetheless. However, "In Person" seems to be the only good album they ever made. They also have "mellow" versions of The Midnight Special, Mule Skinner Blues, and "Whiskey in the Jar" on that album that I value principally for their uniqueness but also for ease of understanding the lyrics. Another pretty song on that album that I've heard nowhere else is "Rolling Home".
