 World War I may have been the high @-@ water mark of music hall popularity . The artists and composers threw themselves into rallying public support and enthusiasm for the war effort . Patriotic music hall compositions such as " Keep the Home Fires Burning " ( 1914 ) , " Pack up Your Troubles " ( 1915 ) , " It 's a Long Way to Tipperary " ( 1914 ) and " We Don 't Want to Lose You ( but we think you ought to Go ) " , were sung by music hall audiences , and sometimes by soldiers in the trenches .
