Where to begin? I've always liked Betjeman, I've had his Collected Poems (Enlarged Edition) since 1976. I still have my copy of Comic and Curious verse from the 5th year at secondary school. Lurking somewhere are a couple of the Griff Rees Jones BBC books. Of course we had various Ladybird books and can recall bits of the poems the kids loved.
Some of the poems describe the origins of this book, dip in, have a read, look me up on facebook using youmustbejokingtoo. How that name came about is a story in itself, perhaps that will be in the next book.
