For those worried that John Harris was forever lost to the Guardian's comment pages (doing to the Lib Dems what he used to do to Menswear), comfort is at hand. It wouldn't be fair to call this a companion to his excellent history of Britpop, The Last Party. Rather, the spectre of Schott's Miscellany looms large - or any other yellowing compendium of rock trivia. But it looks handsome, it contains a "teach yourself guitar in an hour" guide (the bass in half an hour), there's a chapter on the Beatles (full marks for the diagram of Apple HQ at 3 Savile Row), and in revelling in what Spinal Tap called "the majesty of rock, the mystery of roll", I learned about another fictional band: The Archers' Dross.
