Deep Night
It's good to hear this terrifice song in this film along with the Rudy Vallee redition on Bonnie and Clyde and Drugstore Cowboy.
There is no "off" position on the genius switch.
There is also a video, on U-tube, of Ina Ray Hutton and her band performing "Deep Night" on her 1956 TV series.
I know the song has been around for a long time but I didn't know it was ever used as theme music in a film noir movie. It sort of fits though.
