The problem with conspiracy theories is that they quite often don't fit the facts
Ewan never discussed his army career (or lack of it) with anybody; he considered it a private matter. When he was interviewed for Irish radio shortly before his death, he made that quite clear to the interviewer, Tom Munnelly. It is extremely unlikely that he would write about it to any extent.
The same goes for his marriages and his children. Peggy has written on a number of occasions of his relationship with his children, leaving no doubt that he would not have attempted to deal with the subject in an autobiography. As for writing of his failed marriages; to his great credit, it was not that sort of book and he was not that sort of person.
Regarding the disbanding of the Critics group; (not acrimonious, as some people have claimed) while he said several times that the work he did with them was the happiest and most rewarding, of his life, the way in which the acting group, which followed on from The Critics, disintegrated was extremely traumatic for him. On his obituary television programme one of his sons described the affair as leading to him having a breakdown. I believe that, to the end of his life the failure of the acting group, and its association with The Critics made if far too painful a subject for him to write on at any significant length.
Personally I found Journeyman somewhat unsatisfactory; at best, particulary when dealing with his pre-folk days, it was stunning. For me, the latter section fell short of dealing with his work and ideas on singing. On occasion it was Ewan at his most self-indulgent and playing to the audience.
In 1978, Pat Mackenzie and I embarked on a long series of interviews with him, which spread over six months.
During the course of these, Ewan suggested that we might write his biography - an idea we considered and then rejected, mainly because we regarded it as being beyond our abilities, but also because there were too many no-go areas in his life to make such a work anything but incomplete.
Class Act to some extent addresses the omissions, but this falls short of dealing with Ewan as a creative and revolutionary (in the politcal and non-political sense) artist.
