All together, now: "O what can ail thee, knight-at-arms,/ So haggard and so woe-be-gone?" Or here's another: "But at my back I always hear/ Time's winged chariot hurrying near . . ." Practically anywhere you open this book, you'll find a poem you once loved and have since forgotten, interspersed with cleverly chosen new kids on the block such as Tony Harrison's "The Earthen Lot" and Paul Muldoon's "Quoof"; they've all been included for the sheer joy of saying them aloud, and if you try it, you'll find it works every time. A worthy successor to the two marvellous volumes in the same series, By Heart, in which Ted Hughes illustrated how important imagery is to a poem's memorability, and The Funny Side, Wendy Cope's choice of 101 humorous poems.
