PITTSBURGH â The coming weeks will see the culmination of a journey Billy Porter began in 1994. Back then, the 51-year-old Pittsburgh native was living in New York City and playing Teen Angel in the Broadway revival of "Grease" "with 14 inches of orange rubber hair on my head stomping around like a Little Richard automaton on crack," he said in a phone interview last week. During that period, Porter caught part one of Tony Kushner's two-part play "Angels in America" and immediately connected with the character of Belize, a Black, gay, ex-drag queen who became a nurse on an AIDS ward floor. He realized Belize was "a representation that I had never seen before" and he vowed to do that kind of work going forward.
