I've just had a listen to several versions on youtube as well as those above. There are quite a few unexpected versions - Townes van Zandt, The Specials (I quite like this one!), Roger Whittaker, Steve Earl, Richard Thompson with David Byrne!

I must say I hated Ewan with Alan Lomax and the Ramblers (the Plodders?) and while I'm not a great Pogues fan (though I think Shane McGowan can write good songs) I did quite like their version.
