My old copy has no cover, so I had to look inside, it is a 1961 reprint of the 1959 original. It was sitting on the shelf next to the Penguin Book of Canadian Folk Songs. It's not that I am organized, it's just that the books are about the same size.
I sure will be buying the new one, but I will have to buy another pack of toilet rolls to interleave in what looks like MOST of the pages.
Well done Malcolm, JohnB
