Two things spring to mind:

1) The best version I have ever heard was by Fred Wedlock and Mike Evans, which they recorded on a (home-made) LP that they sold on their tour - about 1975

2) There was a version popular in the 70s which had an elaborate chorus, which went something like:

Hello,hello,hello,hello you coal-black smith You do to me great wrong To think to have my maidenhead which I have kept so long I'd rather die a maiden and be buried in my grave Than a lusty dusty ?????? coal-black smith My maidenhead should have.
