The Joe Gordon lookalike in the photie was in fact Jackie O'Connor. Don't know who the woman was, but not I think Gordeanna. And as far as I know Matt McGinn was never on a Faslane demo. He's not on that cover. The names I give above all are, I'm fairly sure.
I may not be the Ewan McVicar, but I'm the only one I know.
Susanne, the listing suggests you have a Nat Joseph release of the Folkways album. Never knew there was one! Nat would not have bothered with a booklet, of course.
