Look at Dougie's website http://www.dunkeld.co.uk where you can obtain the Interactive Songbook Volume 1. It's a CD-ROM and has not only the lyrics and chord charts (in the correct tunings) of ten of Dougie's songs (including Caledonia and Turning away) but also video footage of Dougie demonstrating the fingering and chord techniques. Even I managed to get the intro to Caledonia, so it must be good!

It's about twenty quid and a bargain at that. JB
