Well Phil, I also would love to get some (accurate) tabs....although I have worked out some of the songs for myself. Sadly, a lot of the ones I've found on the web previously just haven't been good enough....or in some cases were totally off the mark!
Anyway, a couple of points to bear in mind....
Firstly, I don't know if you're aware, but Cormac plays his guitar STRUNG upside down. He's left handed, plays a right-handed guitar, but leaves it strung as a right-hander. So this makes it very confusing to try and fathom out what he's playing just by watching him!
Secondly, I once asked Cormac if he used any alternate tunings for the 'On The Turn' album, as I could never seem to get the same kind of 'twang' when playing the songs. He said it was just recorded in drop-D.....but he said the fact that he plays his guitar upside down maybe makes it sound slightly different (the strumming is different).
