This is an Appalachian folk song originally known as Little Sparrow or Tiny Sparrow. Van Ronk calls it swallow here. It is also know as Come all ye fair and tender ladies. There are so many great covers including Peter, Paul and Mary, Odetta. Aretha, The Chieftans and more. But Gene Clarke and Carla Olsons' rendition will always be my favorite. The great Van Ronk does a nice job with it here too.
