Well the truth is,IMHO, 'round our way if they could sing and play well enough to garner an audience then they'd be a performer who does original material. If they could write songs memorable enough to be performed by others then they'd be a songwriter. A singer/songwriter is usually someone who isn't either. now I KNOW that's black and white and leaves out the middle but that's the reason I cringe and go elsewhere when I hear "singer/songwriter.
