After my rant, I guess I should provide some useful information...There are (as far as I know) 2 different Carthy versions, the one on 2nd album, and the more recent Waterson:Carthy version.
I'm guitarless at present so can't help directly with either.
I can however point you towards this page which has (amongst other fab tunes) Stefan Grossman's guitar arrangement of the song.
