Unfortunately, there's no listing of any song that comes close to that title in either the ASCAP or the BMI listings.
Robert Arnold Israel's listings are huge naturally. He's credited with the Password Plus Theme and Password Plus BG Cues published by Keep Music Co. Keep Music is a fictitious name of Mark Goodson Productions.
The only other name attached to both Password and Keep Music is Robert W. Cobert. Cobert wrote the original Password theme, IIRC.
The Library of Congress' search engine is down for the day now until tomorrow. I'll see if I can't dig up anything else from there.
Well, I tried, at least.
