Rhonda Weiss and the Rhondettes
From the TV show Saturday Night Live. Sixties-looking girl group of Jewish American princesses who sing "Goodbye Saccharin," an ode to their favorite low-calorie sugar substitute in the opening skit of the 03/19/1977 episode. Saccharin was briefly under suspicion at the time of causing cancer in lab rats. Now we know that you can safely eat up to 12 pounds of it a day. Gilda Radner was Rhonda Weiss. The Rhondettes were Jane Curtin, Laraine Newman and that week's musical guest, Linda Ronstadt.
The song and group also appeared on Gilda Radner's 1980 live concert film and the soundtrack album, Gilda Live
