“RuPaul’s Drag Race,” she changed the life of legendary New York club director Steve Adelman.Adelman had booked RuPaul to perform at a club in Boston and she had such a good time that she went back to NYC and recommended him to the assistant of the owner of the Roxy, just as the West 18th Street club was opening up.“But I think she highly over-exaggerated my credentials,” said Adelman, whose new memoir “Nocturnal Admissions: Behind the Scenes at Tunnel, Limelight, Avalon, and Other Legendary Nightclubs,” was released this week. “So I appear at the Roxy with a hockey duffel bag, and I’m anointed director.”That twist — or, make that twirl — of fate in 1989 led to Adelman suddenly being a professional partymeister overseeing the dance-floor revelry and debauchery of New York nightlife’s glory days in the ’90s.
