Several different recruiting songs with the name "Your King and Country Want/Need You" were popularised in Britain at the beginning of the First World War.
Your King and Country Need You was a popular song and recitation, with words by Paul Pelham, and music by W. H. Wallis and Fred Elton, published in London at the start of the war in 1914 by Lawrence Wright Music.
[1] It was written as a recruiting song with the aim of persuading men to volunteer to fight in the War.
Half the profits on the first 100,000 copies were to be given to the "H.R.H.
Prince of Wales' National Relief Fund".
