Don Black tells the fascinating story of Ivor Novello and the song that made his name. Keep The Home Fires Burning marks the centenary of a song that became popular both in the WW1 trenches and on the home front, and continued to be sung by soldiers in conflicts well into the 1950s. The programme features the best Ivor Novello tunes, some extraordinary Imperial War Museum archive and explores how music was used as a morale booster in the First World War.
