Well, I found it on an album called Into My Own Thing: The Jewel and Whit Recordings, 1966-1971, by Bobby Powell. It's a R&B recording - I thought it would be a sentimental old thing, but it turned out to be pretty good.
There's a girls' chorus on the two..., two...., two.... part in a cutesy sort of way, and then Powell sings the "No one will ever know" in a bluesy fashion.

Got all that?

But then, there's a boy's version with the same lyrics, recorded by Gene Autry - and it sounds like this (click)

So, there is a country version of the song, and a R&B version. the lyrics are posted above.
