I originally learned the song from a Rambling Jack Elliott album, but it turns up all over the place, including such folk music luminaries as Art Garfunkel ( a somewhat prettified version on Angel Clare, his first solo album ) and the Everly Brothers.

At the back of my mind is a derivation from an early ballad (Child?) under the title "The Oxford Tragedy" - I'll have a dig around on that and post any findings.
