I note that not all the readers reviewers liked this, and although the 1930's original "1066 And All That" is rightly acknowledged as a classic, the effect of this kind of parody is always likley to be amusing rather than belly-laugh funny.
True, some of the puns are overly and sometimes unnecessarilly contrived, but there are some good moments: Grandhi walking round India "stirring up inaction"; Jesse Matthews, unexpected victor of the 1936 Olympics; the coronation in black and white, "as colour was still strictly rationed"; British World War 2 pow's, permitted nothing but "a selection of ropes, false passports, fancy moustaches, German phrase books, a selection of pantomine costumes, a wooden horse and a couple of gliders".
My favourite characters: Alexander Gissa Bell, and, for some reason, my biggest personal laugh: "the Webbs, Donald and Daffy" (bit of an historians' in-joke, that one); most obscure pun, Admiral Duncan Donitz; and Most Memorable event: the end of Mrs Thatcherism; her "loyal ministers" have individually "told her she was absolutely marvellous, but that she'd possibly be even that a little bit more marvellous if she left and never came back. She took the hint, opting to make a dignified exit from Downing Street, howling in tears, hammering on the windows and waving a blue hankie through the back windscreen of her locked car".
Nearest the knuckle of bad taste are the attempted Princess of Wails jokes, one of which makes you wince but is aimed at Tony Blur and hits the mark. Most painfully satirical are the French Resistance jokes: "under the brilliant guise of collaboration" the French "performed well disguised acts of resistance such as entertaining Nazi stormtroopers in their homes and turning in Jews". They also whistled the Marseillaise in the streets, but "for maximum impact", in 1946. Ouch.
The exam papers are better than the original, surreal and spot on, particularly the absurd sources questions (and I've marked a few). It was a brave decision to update the original, but someone had to. It may not have worked. On the whole, this does. A worthy sequel. "1066 II."
