I found a copy of the book in a local shop (midlands, UK). I did not buy it. The Nic Jones content is mundane (one of the songs, as I recall, is merely the lyrics and chords) and a very small proportion of the whole. Mike Raven's website lists Nic's tunings and capo positions for a large number of his better-known songs - a good Internet guide to open-tuning chords will provide the palette Nic was using in a particular case, and you can experiment from there. The Raven website also describes how Nic achieved that percussive sound.

I have found tab for Canadee-i-o - use the title in Yahoo and it finds it (can't do blue clickies) which is reasonably accurate and gives some of the techniques which make Nic's sound unique and which can be adapted to other songs.

Why not make the Nic Jones version of a song the basis for a version of your own, rather than attempt to copy the master?
