And I Am Telling You I'm Not Going - The Cast of Dreamgirls (1982)
Upon seeing the Dreamgirls film and hearing the original score for the first time, I declared that no one could sing this song except Jennifer Hudson. Then a patient friend showed me the clip below from the Original Broadway Cast, and I discovered Jennifer Holliday. Now I know better. Holliday owns this song like Sinatra owns "My Way" and Marilyn Manson owns "The Dope Show"..... 'nuff said. Let's listen!
