Nice video on YouTube of a version of Courting Is A Pleasure by 'Litegauge' at http://www.youtube.com/watch?v=GHU1DSiygYM - it's not too difficult to work out what he's doing. I've used CGCGCD and it's close (at least as close as a duffer like me can make it!). Trying to imitate Nic's style is going to be difficult (see remarks in related threads). Get the gist of it and make your own version, and enjoy singing/playing the song - that's what's important in folk music, isn't it?
