Christmas Mystery – Still Unsolved

I remember listening to Fanny Brice on the radio as a child. She was the star of a “program” called “the Baby Snooks Show.” When she decided that she had enough of Baby Snooks, she made an announcement on the radio and went off to Valhalla. I was heart-broken when she quit. I never heard from her again and did not see the connection between the Barbara Streisand film (Funny Girl; which you probably get on NetFlix) and her. I remember that all the kids in the neighborhood were sad at her leaving radio. Soon after TV became popular and Fanny faded into the mists of time.
