Same here. I had watched The Doctors occasionally before Nancy was on but I watched it on a regular basis when she joined the cast. I also remember Armand Assante, Gil Gerard and Julia Duffy. I had stopped watching by the time Jim Storm was on the show. To say nothing of Kathleen Turner.
Did you ever see Virginia Vestoff on The Tonight Show back then? She sang something from 1776 (I presume.). She discussed replacing Elizabeth Hubbard. There was some sort of crisis that found Nick Bellini in jeopardy. Hubbard's Althea walked out of wherever she was, saying that she was going to take care of Nick. Vestoff's Althea came back and took care of Nick.
