Simon Elmes celebrates the great, the forgotten and the notorious voices of radio from the last nine decades. His survey runs from Marion Cran in the 1920s, who pioneered the first gardening programme to Lord Haw Haw, whose sinister catchphrase ‘Germany calling’ punctuated broadcasts throughout the Second World War; and from the Goons and Kenneth Horne, comedy greats of the 1950s, all the way up to Eddie Mair, Fi Glover and Danny Baker today.
