I believe Nic played it in CGCGCD as per john c's post above which I've never tried. I've tried it in DADGAD (my usual tuning) but can't get a good approximation. Maybe you can help me there Willie-O! I had a much better fit with EADEAE for this one and for a lot of others that I'm not quite happy with in DADGAD but it certainly doesn't in any way sound like Nic's version.

All the best,
