In January 1914, Rachmaninoff began a concert tour of England which was enthusiastically received. He was too afraid to travel alone following the death of Raoul Pugno of an unexpected heart attack in his hotel room which left the composer wary of a similar fate. Following the outbreak of war later that year, his position of Inspector of Music at Nobility High School for Girls put him in the group of government servants which prevented him from joining the army, yet the composer made regular charitable donations for the war effort. In 1915, Rachmaninoff completed his second major choral work, "All-Night Vigil" (Op. 37), after he attended a performance of the "Liturgy of St. John Chrysostom" and felt disappointed with it. After spending two weeks writing the "All-Night Vigil", he passed the score to Sergei Taneyev for proofreading and correcting errors in its polyphony, but it was returned unaltered. It was received so warmly at its Moscow premiere in aid of war relief that four subsequent performances were quickly scheduled.
