I've used the search quite a bit for this, but I haven't been able to turn anything up. Does anyone happen to know the tuning Martin Carthy used in his "Shearwater" recording of "Famous Flower of Serving Men"? I saw a tip somewhere that it was in open G, but I tried that and couldn't make it work. I'm actually less interested in playing the song than I am in understanding how it's played (since I can't think of a situation where I'd be welcome to play all 20-odd verses, even if I were somehow to master it).
