Former Wiz star Stephanie Mills will be Seth Rudetsky's special guest at the Oct. 3 edition of Seth's Broadway Chatterbox.

The weekly live talkfest, which includes interviews and performances from Broadway stars, is held at 6 PM at the New York cabaret Don't Tell Mama. There is a $10 donation and a two-drink minimum. The donation goes directly to Broadway Cares/Equity Fights AIDS, the nation's leading industry-based, not-for-profit AIDS fundraising and grant-making organization.

Stephanie Mills made her Broadway debut in the musical Maggie Flynn, but it was as Dorothy in the 1975 production of The Wiz that brought the singer-actress much acclaim. Mills reprised her role in the 1984 revival of the musical, and she recently appeared in the all-star Funny Girl concert to benefit the Actors Fund of America. Also a recordings star, Mills had a worldwide hit with the song "Never Knew Love Like This."

Creator and host of Seth's Broadway Chatterbox, Seth Rudetsky has served as a pit pianist and/or conductor for such Broadway shows as 42nd Street, The Full Monty, The Phantom of the Opera, Mamma Mia! and The Producers. He also conceived the idea for the recent all-star Funny Girl concert to benefit the Actors Fund of America as well as last season's Dreamgirls anniversary concert. Rudetsky was a member of the comedy writing team for "The Rosie O'Donnell Show" for two years, and his awards include the Duplex's Stars of Tomorrow, the Backstage Bistro and the Funniest Gay Male in New York.
