Simon and Garfunkel's "Scarborough Fair" - is probably the most famous of the modern versions. It's certainly the one I think of whenever I hear the line "parsley, sage, rosemary and thyme."
It's interesting to see that they used a vocal counter-point borrowed from an earlier anti-war song by Simon.
This vid shows the lyrics. The "anti-war" counter-point is almost impossible to hear, even if you know to listen for it. It makes a beautiful sound, the background lyrics, and perhaps is a subliminal message, too.
This version, by the Gothard sisters (who are not triplets), is just for fun.
