My father did a lot of singing of various types of songs. When he was puttering around the house, he would often be singing a couple of lines from one of these:

1) Our Sergeant-Major (His medals broke our hearts/He won them playing darts - in fake George Formby accent);
2) Passengers will Please Refrain;
3) Dirty Yankee Miners (a Cape Breton labour/protest song);
4) Madamoiselle From Armetieres.
