The song "To Morrow" in the database is a slightly different version of the one I heard, but not enougth to speak of, really. I couldn't find the "Nobody's Business" that I know. It's a man and a woman singing back and forth to each other and the only part I can remember is:
"You've got a gal you love on Monday Then you've got another on Sunday-"
"Ain't nobody's business, but my own!"
Nobody's business Nobody's business Ain't nobody's business, but my own!
It's a silly song, but those are the best kind.
