My significant other, Rika Ruebsaat, is writing a thesis on the words of songs taught in BC schools since 1900. This "Freedom Isn't Free" song (though only two verses) turned up in one of the texts, "This is Music for Today (Canadian Edition) 7." (1971)I've been entering in our big database. I figured they put it in to counteract the dreadful communistic, anarchistic, black-dwarf-lesbian-loving effect of the previous song in the book, "Where Have All The Flowers Gone?" by the well-known Peter (sic) Seeger.
