Ok, John Clark then. Makes sense. Tom Varner didn't fell right I like John Clark a lot more, then and now.
And I do remember Ehrlich now, I knew there was somebody else up there. But I have no recollection of Parran whatsoever. So Ehrlich was on clarinet and Lancaster was on bass clarinet. Very distinctly remember that because it had no bell. An odd visual but a great sound.
And definitely James Newton on flute. You don't forget that!
So yes, that's my final answer - Jenkins slightly front and center, with L-R behind him being , Clark, Newton, Ehrlich and Lancaster.
Very strong group.
