Dave,
haven't heard of Kirsty MacColl and you call yourself a Folk
music admirer?
If you were then you'd have also heard of Luka Bloom, Christy's nephew.
I've seen him live and he's brilliant.....It's in the blood obviously.
Two truly talented musicians.
As for Kirsty, see if you can find a duo with her and Shane McGowan
(Pogues) on youtube...Fairytale of New York...brilliant song.
