Almost a plug then thought better of myself Dave! Hence the self edit of my post!
Truth is, it's a complex / vague story for each of their four recordings, indeed anything about the Appreciations, and I don't have the full story myself, but a fair bit more than was known previously (took best part of a year to get hold of one of the band members). Suffice to say their story involves NC, SC, Detroit, Nashville and the sax player? And may well not have been Mike Terry contrary to popular belief, including mine, but somebody else who will be surprise to some.......
