Didn't think it was Derek - I said there were a series taken at the time of the making of 'Singing the Fishing' and wondered whether the one in the new book compared in any way - will look when our copy arrives (thanks, btw)
I know that Doc had access to Charles Parker's photos and recordings because of their friendship,
The fact that it is captioned as "Photo: Doc Rowe Collection", makes me suspect that this is one of those.
