Celtaddict,

The verses I recall for "Hot Nuts" were parodies of verses from things like Ray Charles' What'd I Say and older Gospel stuff (Let My People Go?):

See that girl, all dressed in red
Makes her living on a feather bed

See that girl, all dressed in black
Makes her living on her back

See that girl, all dressed in pink
She's the one that made my fingers stink

etc., etc.,

And that was just the sort of thing we'd sing on the bus (a chara, that is, not the 25 into town), or at the rugby club or students union bar or similar places.
