Lenny Henry's graphic novel

Or, "The Quest For The Big Woof". It came out around about 1991, and my parents got it for me as a Christmas present. I think it may have been related to Comic Relief somehow. It was at least partially written by Lenny Henry, illustrated by a fairly big name in British comics, with a foreword by someone equally famous, but I forget who they both were. The book started with Lenny Henry hitting writer's block and trying to come up with new material. Then God visits him and they sort of go on a kind of adventure, zapping to various parts of the world (including South Africa at one point), and the whole book sort of turns into a kind of autobio thing, centering around the death of Henry's father. Anyway, does anyone else remember this? I seem to be the only person who has ever read it.
