Disco fever affords Goldblum a player lifestyle as owner of the L.A.’s hottest dance palace, and during one wild Friday night on-site he pursues married Andrea Howard. In the house: Debra Winger, deejay Ray Vitte, Chick Vennera, Terri Nunn (later lead singer of the group Berlin), and Paul Jabara — who won an Oscar for his song “Last Dance,” performed onscreen, indelibly, by Donna Summer; also on the bill are The Commodores, with their tasty jam “Too Hot ta Trot.”
