Christine Ebersole also hits the same note when she first sings the word "man" in If I'd Been a Man from War Paint
Close to them would be Betty Buckley in Carrie "When there's no one" though she sings one and half notes higher.
However, Mary Martin sings even lower in Do Re MI, when she descends to do, at the end do ti la sol fa mi re...do, around a third lower than Chita and Christine Eversole
