Great to see this thread re-emerging, and to see I've already added my tuppence worth. See above that I consulted a Swazi storytyeller about it, I now suspect his response was more polite than knowledgable. I recall the Hurrah for the CRE part lyric above, but I do not think it was attached to my I Ziga Zumba version - which I hav taught to hundreds of Scots schoolkids now.
