Donna Summer sings "Bad Girls" a capella

Enjoy disco diva Donna Summer's incredible isolated vocal track from "Bad Girls" (1979). Toot toot, beep BEEP. The song is about sex work and the police. From Gavin Edwards' book "Is Tiny Dancer Really Elton's Little John?":

"I was in my office in the old Casablanca [records] building," Summer told me. "I was the only artist allowed to have an office there — [Casablanca head] Neil didn't want me too far away. I sent out my secretary to do something, and the police stopped her on Sunset Boulevard. She was dressed in business attire, but they were trying to pick her up. That ticked me off. All day, I pondered why that would happen to innocent people–and then I developed compassion for the girls working on the street." And the "toot-toot, beep-beep" that concluded the track? "I figured, what do guys do when they pick up girls? I had to emulate them tooting their horns."
