Mary Cleere Haran, the accomplished chanteuse who had a big success in fall 1998 with her all-Gershwin show at the Algonquin Hotel, will return to that lodging house's Oak Room Oct. 24-Dec. 27 (8 PM Sunday and Monday evenings only) with Crazy Rhythm: Manhattan in the Twenties.

As always, she will be accompanied by Sir Richard Rodney Bennett.

Crazy Rhythm is meant to evoke a bygone New York world of "speakeasies, dance halls, the Ziegfeld Follies, Harlem nightclubs, Broadway's flappers, gangsters, reporters, showgirls and chorines." The show will feature the music of the Gershwins, Gus Kahn, Irving Caesar, Ralph Rainger, Vincent Youmans, Rodgers & Hart and Irving Berlin.

A daily schedule of performances plays Dec. 28-Jan. 8. The schedule skips some dates in November.

Haran's many albums include "There's a Small Hotel" and "Pennies from Heaven -- Movie Songs of the Depression." Cover is $45 with $15 minimum. The Algonquin is at 59 W. 44th Street in Manhattan. For reservations, call (212) 840-6800.
