Nathan will begin her stint as Matron "Mama" Morton Sept. 13 in the Kander and Ebb musical. Nathan, who replaces Roz Ryan, will stay with the Tony-winning revival through Dec. 3.
In addition to Assassins, Nathan originated the role of Miss Flannery in Thoroughly Modern Millie (audiences embraced her for her no-nonsense turn as the typing pool matron, her conical wig and a tap break in the middle of "Forget About the Boy" in Act II). Her other stage credits include Ragtime, Swingtime Canteen, Les Misérables and Aspects of Love.
