The Los Angeles run of John Kander and Fred Ebb's musical will play through Feb. 20 at the Pantages Theatre as part of the Broadway/ L.A. series.

LaBelle — who will portray Matron Mama Morton for the exclusive engagement — is known for her Grammy Award-winning rhythm and blues songs which include "On My Own" and "New Attitude." The one-time lead member of the group Labelle also sang on the group's biggest hit "Lady Marmalade." The singer has appeared on Broadway in three self-titled concerts and appeared in the 1982 revival of Your Arms Too Short to Box With God.

Brady is known for busting out into song as that host of his talk show "The Wayne Brady Show" and for his improvisational skills on ABC's "Whose Line is it Anyway?" The comic actor will reprise his Broadway debut performance in the role of Billy Flynn for the L.A. run. He has also guest appeared on television's "I'll Fly Away", "Home Court," "In the Heat of the Night," "Chappelle's Show" and emulating Jackie Wilson on "American Dreams." His stage credits include productions of A Chorus Line, Fences, I'm Not Rappaport, A Raisin in the Sun and Blade to the Heat.

Brenda Braxton stars as Velma Kelly opposite Bianca Marroquin who returns to star in Chicago as Roxie Hart — a role she played at the Pantages last year.

Chicago won the Tony for Best Revival of a Musical in 1997 as well as awards for actors Bebe Neuwirth and James Naughton, director Walter Bobbie, lighting designer Ken Billington and choreographer Ann Reinking. The original production was directed and choreographed by the late Bob Fosse. Chicago will play at the Pantages Theatre, located at 6233 Hollywood Blvd, (between Vine and Argyle Streets). Tickets are available through the Broadway/ L.A. website at www.broadwayla.org. Note: Ms. LaBelle will not appear in the production on Feb. 4 and Feb. 18.
