R. H. Gardner, the longtime Baltimore Sun theatre critic, wrote an article on Agnes of God on Broadway after the opening. He felt that the Broadway production was played too much for laughs. His review of the Center Stage production and The Best Plays of 1980-1981 both list Tania Myrem.
Doing a bit more searching, I found that when the play was given a staged reading at O'Neill Conference in 1979, Jo Henderson was Dr. Livingstone, Jacqueline Brookes was Mother Miriam Ruth, and Dianne Wiest was Agnes.
