Comedian, writer and actor Rob Bartlett will join the Broadway company of Kander and Ebb's Chicago next month. Bartlett, who can be heard on the nationally syndicated radio program "Imus in the Morning," will begin playing beleaguered husband Amos Hart July 9 and will stay with the Tony-winning revival through Sept. 15. P.J. Benjamin currently plays the role of Amos, originated in this revival by Joel Grey.

The versatile Bartlett appeared in the Paramount/CBS comedy specials "What's Alan Watching?" and "Move the Crowd," and he has performed his acclaimed stand-up routine on "Late Night with David Letterman" and in comedy clubs throughout the country. Bartlett also wrote and starred in the PBS special "Robert Bartlett's Not for Profit T.V.," and he penned the play More to Love, which he starred in on Broadway in Oct. 1988.

It 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.
