Same here about the folk clubs back in the 80's... a good friend of ours used to sing it beautifully. I've only ever known it by that title (Willie McBride) but I see it goes by "No Man's Land" too.
The worst thing about the Joss version (apart from leaving out the last verse which was surely the point of the whole song?) is the dreadful video that went with it, with her floating about all in white amongst the Tower poppies - such a travesty!
