All I know is the two lines of lyrics
“Nobody hast to know/Unless it is you that tells them so”
Sound Familiar?
Jesus Loves Me?
lieu, you always crack me up! 
Mudshark, any more clues? Is it new? Old? Rock? A hymn? 
I have no idea on what type of music it is. Probably older, most likely rock (but maybe not, I don’t really know). I think we can safely eliminate hymn from the list.
It’s not verbatim what you have, but a very similar couplet occurs in Call Any Vegetable, from Frank Zappa’s Absolutely Free CD.
Could that be what you’re looking for?

PS If that version doesn’t sound right, try the version from Just Another Band from L.A.
That is it. It is th Zappa lyrics.
I shkuld kick myself, I have both Absolutely Free and Just Another Band From L.A. and Call Any Vegetable is one of my favorite songs.
