Guest,
That only happened with a few waulking songs. Many waulking songs were composed and had typically women's themes for subject matter. Depending on the length of time needed, if you had to improvise, then yes, "gossip" items were filtered in. Usually it would be of the teasing variety. For instance if it was known a girl was longing for a fellow or if they had been seen holding hands, etc, either of their names might be mentioned in extemporaneous verses. Made for lots of fun. Of course this sort of thing was not done when menfolk were around.
