I'm reading "Barnaby Rudge" at the moment. The introduction says Dickens himself had a raven he was very fond of, and Landseer described him as raven mad, which later transmogrified into raving mad. Can anybody confirm this?

I did try the google thing, jmh, but raven mad is also the name of a pop group and I didn't feel up to wading through all the fan pages.
