Watch: Patti LuPone Sings for her Supper at '80s Gay Bathhouse on 'AHS: NYC'

Patti LuPone made news earlier this week when she said she was leaving Actors Equity, the union for performers that is the standard for Broadway performers. With the rise of non-Equity tours, some bitchily speculated that LuPone would soon be starring in a non-Equity tour of "Mean Girls."

LuPone also did a shout out to New York City gay history this week on the first two episodes of Ryan Murphy's new season of "American Horror Story" called "American Horror Story: New York City" that is set in the 1980s. (And, no, it does not feature actor-wanabees singing "NYC" from "Annie.")

The series follows a group of gay men who are finding themselves being connected after a masked serial killer is on the loose in the city's gay neighborhood and leather scene while a mysterious disease is starting to infect and kill LGBTQ people.

No doubt others see a nod to William Freidkin's "Cruising," a 1978 thriller starring Al Pacino as a detective who goes under cover to investigate d a serial killer who is targeting gay men with much footage filmed in the real leather bars in the West Side Meatpacking district long before gentrification.

On "AHS: NYC," LuPone plays the singer at the Neptune Baths, a reference to Bette Midler who famously did her some of her first cabaret shows at Continental Baths, putting the unusual venue on the scene as the source for upcoming talent, who were to include Barry Manilow, Melissa Manchester, Labelle, and Peter Allen.

In the first episode, LuPone performed a cover of Peggy Lee's "Fever" in a room filled with men wearing towels or nothing at all. She returns to cap the episode with the Holly Cole's bluesly "Call Me," which ended the creepy episode.

Her appearance got an immediate response on Twitter.

"Still thinking about how Patti LuPone was singing "fever" in ahs NYC in a bathhouse while gay men were giving and taking it," tweeted user @heyjaeee.

He received a response from actor Joshua Hernandez (@joshuahemandez who was on the set with LuPone sang. "I was on set this day. I was butt naked in a pool and all of a sudden Patti walks on set and starts singing to all the gays. I was gagged. For real."

But this isn't the first time LuPone sang in a gay club in a horror series. On the second iteriation of "Penny/Dreadful," called "City of Angels," and set in 1939, she was cast as a big band singer at a secret gay club singing "Stardust" to a crowd of dancing same-sex couples.

LuPone was earlier a part of the Ryan Murphy universe. "LuPone previously appeared in the show's third season, 'AHS: Coven,' which premiered in 2013. She played Joan Ramsey, a strict fundamentalist Christian woman with a dark secret who moves in next door to witchcraft academy Miss Robichaux's Academy for Exceptional Young Ladies," writes People. She also appeared in "Hollywood," "Glee," and "Pose," where she played nasty real estate mogul Frederica Norman who got to sing Stephen Sondheim's "I'm Still Here" at a hospital benefit.
