HI Charlotte R
In my original post I mentioned that Kathy was probably as close as they were gonna get.

There's much to your analogy with the "Classics" Don. If in fact you were an English Lit professor & your specialty was the classic's & you just read a newly published read, I would say that you might at the end say "this is gonna be a classic" or not. You've been studing them for you whole life, pouring through those that claimed to be but were't & steeped in those that were. You've developed what might be called "a feel" for what is & what isn't. Well, I'd say that some of this feel can be used used along with what would also be a more rational reasoning & explanation. Like what you were saying above.
So many times I've gone to a venue where I didn't know about the said "folksinger" but took a chance because of what the billing discribed or the person at he other end of the phone said only to get there & after 3 or 4 songs want to vomit. My stomack knows the difference.
