She took some singing lessons in her late twenties or early thirties. Since then, her singing has been done in her Parish choir. She did contribute to a CD 10 years ago, that was a fundraiser for a charity in her area. She was asked by someone who knew of her lovely voice, to be a part of it. Since that time, she had taken care of her elderly mother who died a couple of years ago.
Her Parish priest said that because of her mental disabilities, her performances can be erratic, and sometimes she forgets the words. Doesn't sound like a professional singer to me.
I hope she makes several CD's and makes enough money to take care of herself, and her 6 older brothers and sisters in their dotage.
