Someone has contacted me, trying to find a book. The only lines they recall are:
"Porridge piping hot with cream on,
How they loved it, weren't they glad"
This person believed that these lines came from Piggly Plays Truant - but bought the book and found that they weren't. I normally have a very good hit rate at identifying missing books from the odd line or description of a picture. But these words don't ring a bell. Although they do sound as though they could have come from a Perring 401 Bunnikins sort of book, I've had a quick look through most of the 401 series, without success.
If anyone can identify the book, please let me know - by email or leave a comment.
