Terri White is not the same person as Lillias White. Terri can be seen on the VHS/DVD version of Nunsense and Nunsense 2 with Rue McClanahan.
Terri sometimes sings in the clubs in Greenwich Village. One time she sang "Thank God I'm Old" and a woman in the audience was heard saying, "She sounds just like the woman on the cast recording."
If anyone ever tells you that you put too much Parmesan cheese on your pasta, stop talking to them. You don't need that kind of negativity in your life.
