gram Bailey says:
I can only remember that some of the most wonderful voices in music history have come from ladies that did not worry about weight…Cass Elliot, Kate Smith, etc. This women have so much to offer musically that their weight is usually the last worry they have. True musical genius does not concern themselves with the mundane insignificant worries that people with no talent do. A person can be the most wonderful person alive and someone will always be criticizing them. That is what jealousy does.
