I think the book about the Codona family (Scotland's leading family of circus and fairground people) is now out but I can't find a reference to it on the web.

(And can I find that Rodger image? No, but I did discover the Magnum page gives you an extraordinary bunch of pictures if you just type "clarinet" in the search box).
