"When My Blood Runs Chilly and Cold" is a Negro spiritual from slavery days. As with most spirituals, the source is unknown. The first printing was in R. Nathaniel Dett's Religious Folk-Songs of the Negro as Sung at Hampton Institute (1874). It was printed in both of John A. Lomax and Alan Lomax's American Ballads and Folk Songs (1934) and Folk Song U.S.A. (1947). It was recorded by Mississippi John Hurt on D.C. Blues Library of Congress Recordings, Vol. 2. The chorus is very close to the "Do Lord" spiritual that we all learned early on in Sunday School.
