As part of the new program's "Second Cup Cafe" series, the Tony Award-winning actress will be interviewed and sing two numbers from the Broadway musical now playing the Walter Kerr Theatre.
Accompanied by the Grey Gardens orchestra, she'll perform live in the show's second hour.
"The Early Show" is seen in the New York City area on Channel 2 between 7-9 AM.
Viewers across the country should check local listings for times in other cities.
In the new musical by Scott Frankel, Michael Korie and Doug Wright, Ebersole plays two roles — the poised matriarch Edith Beale, hostess for a grand party at her Long Island estate called Grey Gardens, in 1941 (Act One); and her middle-aged daughter, Edie, an eccentric, broken creature in 1973 (Act Two).
