Susan Werner is/was a Philadelphia based folk singer. She seemed to rise quickly from obscurity about 3 or 4 years ago. Her music has become quite "pop" sounding and I suspect she'd love to sing jazz. She has at least 3 CD's and you can probably do a Webh search with her name. She surely has a web site. I'm at work, or I would do all of that work for you.
