I don't sing... but I do play in a band with a stated goal of playing Irish traditional music (even though none of us are Irish and we have an inescapable American accent in our instrumental playing.


So here's my question: If a singer with a pronounced American accent (southern, Texas, New York etc) sings an Irish song with a band where the musicians are all playing with appropriate ornamentation - wouldn't that sound pretty weird? Not that the singer should force the an Irish accent, but shouldn't they at least de-emphasize the American sound? Same if they were singing Scottish songs and playing Scottish traditional tunes.   

What do non-Americans do when they perform country and western music? Do they put in a "twang" and try to sound like American country singers? And would American country singers feel that was inappropriate or disrepectful or laugh at performers who did that?

Just curious....
