OK. First off, this may be the gayest thing ever posted on this site. At least today. Secondly, it's a link to YouTube, and one of our unwritten rules is that we do not link to video because it requires more than 11 seconds of your attention.
That said, here's Jennifer Holliday performing "And I Am Telling You (I'm Not Going)" from Dreamgirls from the 1982 Tony Award broadcast. No matter that she looks like a black Mrs. Lovett, we dare you not to be completely awestruck by what's been called one of the finest theatrical moments ever.
