Who's take on it?
As it's reckoned to be something like 300 years old, there are way too many versions of this to give any kind of general answer.
FWIW, I'm of the opinion that it needs a really minimalist approach; it's a very dark song (at least for the first half) & the vocals need to be right at the front. The second part can be livelied up a bit, kinda like a New Orleans funeral.
