I had never heard of her. However, watching the Jonny Carson clip, I felt like I had seen her before but I can't imagine where. She is three years older than I am so I would have been too young to remember her. Maybe it was just seeing the old Jonny Carson set that made me think I had seen her. I'm old now. I don't know!
I'm still thinking of that performance, though, on Jonny Carson. Seriously. She had major talent. She didn't 'act' while singing that song, like so many child stars aka pageant girls
She became the song. You can't fake that. Totally brilliant and amazing.
