I put my order in as soon as I saw this (thank you much for the heads-up). Sadly, despite living in Edinburgh, I've found it impossible to get my sticky mitts on a complete 8-volume set. I believe several volumes are now out of print, and the publishers told me last year that they have no plans to reprint, which is a shame. Maybe this new book will stimulate interest and change that.

Anyway, I've just stumbled across this, which might be of interest. If nothing else, it shows the songs that are in the new book.
