Yes! "Singing Together" rings a bell and it could well be published in one of them. I see there are four copies from the fifties going on e-bay (could it be in one of those?)

Other songs that I remember singing from the school (but not necessarily the same year) were "Old Zip Coon", "Billy Boy", "Barbara Allen" and one about driving to a market on a Friday which I think was Dutch. This would suggest "Singing Together" if, as you mention, they incorporated overseas folksongs.

Thanks MCP for the index - tried 1960 & 61 (after that I went to secondary school) some familiar ones there.
