They just give the verse that "Tocher" printed too.

I've found a bit more background. Seems the woman of the house where MacCormick heard those songs did in fact waulk with her feet, and there is a report in the proceedings of the Crofting Commission from the late 1890s where she was complaining about being put off her croft when they extended the granite quarry - the site of her house is now a large hole in the ground.

It would be particularly interesting if MacCormick's versions of those songs (which I presume are known from elsewhere) worked in any local references.

I might try asking Joy Dunlop what she knows; that was a good find.
