Trying to identify a comedian seen on HBO in the 1980s or early 1990s. He is gay and diagnosed with Aids. In the routine, he also stated he hosted at a comedy club in LA.
You might mean Steve Moore, a gay stand-up comedian with HIV who starred in the HBO comedy special Drop Dead Gorgeous in 1997. Sadly, he died a couple of months ago. You can see a bit of his act here.
