Heather Headley, Audra McDonald, Tamara Tunie and Lillias White are the divas at the center of Dreamgirls. The four, three of whom are Tony winners, performed for the Aug. 14 press preview of a special Actors Fund benefit staging of the musical to be held Sept. 24 at the Ford Center. Dreamgirls, a high-energy musical from the pens of librettist Tom Eyen and composer Henry Krieger (who went on to write the aforementioned Side Show), tells of a Supremes-like singing group that moves from the streets of Chicago to the big time — with lots of infighting and heartbreak along the way. Songs include "One Night Only," "I Am Changing," "When I First Saw You," "I'm Somebody," "Family" and Effie's show-stopping "And I Am Telling You I'm Not Going." Darius de Haas, Norm Lewis, Billy Porter Alice Ripley and James Stovall will also star in the Actors Fund benefit.
