Very interesting reading of a subject dear and to near to my heart. I've hosted some premium mics and performed at many others. I can identify with all the previous comments. I've had to learn how to survive the above subject I would call rather a lack of etiquette. Each of us be we song writers or cover players hear each song our own special way. Our aim is to share the special way we each hear with folks who try to listen. To me anyone who attempts to tread on this very individual sound is a bore or cretin. How dare they think they could aid or improve MY music is my stance. I offer this concept to you. I silence them quickly and forcefully whatever their intent may be. They don't ask, nor do I. I first request them to stop the NOISE. (as I've had to do even with Dylan a few times and run him off the stage believe it or not, tho t'was long ago) If that fails to gather their attention I say I will begin again when they are done making a mockery of a music they cannot possibly know the details of. Were a premium player/singer to ask me assist (that has happened now and then) I decline, not because I can't play or sing their style but because I would prefer to hear their masterwork unimpeded by myself or any other... pure as I see it. It's a simple concept, when you listen you learn. Over the years becoming tired of having to deal with these bold or drunken bores I have kept my instruments and my cool tuned together but off of standard 440 pitch. It drives them visibly nuts as they frantically try to find the key. When the true listeners catch on it's a laugh riot. Problem thus solved by the attentive, nuff sed. Try it! Fair is fair, is it not? :) M'Tyme
