Patti LaBelle, left, Dustin Lance Black, right.

Among those who will be entertaining us this weekend at Dallas’ Black Tie Dinner will be two entertainment icons with very different backgrounds: R&B legend Patti LaBelle and Oscar-winning screenwriter Dustin Lance Black. But each in his or her way has had a significant impact on the gay community.

So for this special edition of Show vs. Show, we decided to figure out what they will bring to the table during their appearances: LaBelle as the featured entertainment, and Black at the featured speaker.
