I heard this song from Jimmy McBeath when regularly at the Aberdeen Club.The tune has always been in my mind,as a version of the Donegal song Glen Swilly,which I got from an Irish worker at the Mauchline creamery in 1959 in my student days.Jimmy used to sing "broon's a toad" but it could have been Tod.or fox,anyway he had his own unique orally transmitted versions and probably made a few phrases up along the way!
