I call Jay the really loud singer: "Jay The Really Loud Singer," but Marshall Richards, the "New Orleans Opera Guy" is either louder, or just sounds louder because he is clearer.
It's a matter of range also, in the way that a crow's caw might sound louder than a cow moos, but you can probably hear them both from as far away.
Marshall would be the crow in that scenario.
Marshall has become a good friend of mine after his getting over a slight bout of the "if you don't do classical, you ain't s***" mentality.
He likes to drink, so we have that in common...
