Btw, I think you shortchange others on this forum. There are many participants here who, for (I assume) various reasons, choose not to participate in this thread.

These are your words, could you please expand on them; they allude to some mysterious reason others who are jazz aficionados choose not to participate in this particular thread; could you expand on your own words.
