One of the brightest lights in American musical theater for over a decade, actress and singer Christine Ebersole was a Tony Award-winning performer who wowed critics and audiences in productions like "Dinner At Eight," "42nd Street," and "Grey Gardens," for which she played two challenging roles. Ebersole also enjoyed a career in film and television, most notably as a Not-Ready-for-Prime-Time Player on "Saturday Night Live" (NBC, 1975- ) during the troubled 1981-82 season.
