My somewhat limited repertoire consists of mainly blues songs which obviously originate with black singers. Does the team think that it's unethical to sing in an approximation of a black singers voice and/or to "tidy up" the lyrics.
Maybe I should just get on with it. A guitarist friend of mine who worked in a bank and played in a local folk group berated me for "trying to sing like a negro" I in turn berated him for "trying to sing like a farmhand/sailor etcetc".
