"Reuben James" uses the same tune as "Wildwood Flower" ~ if you want to avoid the American WWII patriotic fervor, go for teh Carter Family version.

Also, speaking of Carter Family versions, "Will the Circle Be Unbroken" is sung to the same tune as the older spiritual "Glory Glory Halleluiah (Since I Laid My Burden Down)."

In both cases (and others I'm sure), judge your audience as to which chorus lyric they're more likely to enjoy singing.
