'Tisn't.

For detailed discussion re "I Know You Rider" being a distinct and different song, see thread 40592 cited above.

"Woman Blue" as given by Sandburg is nothing like. Simply two early floating blues verses, unrelated to "I Know You Rider."

True, the Lomaxes called the "I Know You Rider" original by the same title, "Woman Blue," but that was an offhand name without any particular integral relationship to its internal content -- in other words, the title didn't belong to the song. Which is why I retitled it "I Know You Rider" when I began performing it in the 1950s.

This is a tangled question! But to put it most simply, "Woman Blue" (Sandburg) is no more related to "Woman Blue" (Lomax) / "I Know You Rider" (rev. and arr. Bob Coltman) than any other two early blues are related to each other. They share mood, feeling, but not song family.
