Passing strange that it didn't occur to me, since I Google as much as the next guy. Could it be that, in contemplating the question, I had cast my mind so thoroughly back to 1974 that online avenues of inquiry did not present themselves as considerations? Could it be that I'm looking for a complicated explanation for a simple brain-fart?

Anyway, I stand amply corrected.

cordially,
