There was a song, probably somewhere between 1984-1986, with the hook line: "Everybody knows....Anything goes..." Was it Frankie Beverly & Maze? Shalamar? I am drawing a blank, but I THINK it was on the label that Shalamar was on....here is more :

"Somebody's turned the lights off ...now everybody's in the mood...Nobody's trying to find out....what is what and who is who....beggin and waiting...anticipating..thinking about making a move....what I'm saying....this time we're playing...

(chorus): "It's so easy but, don't ....be too quick to let it go....in the dark....everybody knows...anything goes..."

Thanks for your help.
