Jim Carroll, there is no evidence whatsover that listening to what singers have to say will result in a larger number of better singers, in my opinion listening to the singers, singing is what will result in having a larger number of better singers, your consistently inaccurate remarks, that you do not back up with facts, do nothing to give credibilty to your attempted scholarliness.
listening to what singers have to say is interesting but not as interesting or gripping as listening to their actual singing.
