jim, I'm on tour now and only have a phone for this so i'll be brief. what you say is fascinating and I think you're onto something very important. I'm very interested in the psychology of song and this goes to the very heart of it. I should have said 'booklet', not book. its been published in abridged form by living tradition but u can dowmload it from tombliss.co.uk. I plan some addittions soon, and would like to quote u and others if I may. its just workshop notes now.
