I agree with you jim,. I have never let anyone other than myself decide how I should sing a songAND I have frequently decided to sing a song unaccompanied because theres no better way of doing it. however there are some songs that I perform , for instance[Just as the tide is flowing] That I think work better with my concertina accompaniment.
Many years ago at a club in the rochester,kent area, Nic JONES made a comment to me, a girl singer asked the audience what she should sing. Nic said, you should never do that, you should do what you want to do and perform it well enough to convince the audience you were right [ have a belief in your material]. SO WE AGREE ABOUT A LOT OF THINGS JIM .
