The song is "Your King and Country Want You," a popular music-hall song from the early months of the war. It is sung here by Helen Clarke and is copied from an old phonograph cylinder.

The music halls were an ideal place to appeal through music, recitations and various performances to the patriotism of mainly lower- and working-class young men. Reports say that men would leave the theatres after hearing songs like "Your King and Country Want You" and go directly to the recruiting stations to enlist for military duty.
