I have known for a long time that she is a sister and when I lived in Omaha, NE, I went to help Beta Alpha Chapter in Lincoln they had an autographed pic of her that said " to my sisters" or something like that, I went nuts (
no pun intended). No one in the house had a clue who she was until I started singing friends and lovers, which was her biggest hit!
I had no idea she was still recording though.
