Schirmer has published several alternate arrangements for "Adagio for Strings". They include:   Strickland, while assistant organist at St Bartholomew's Church in New York, had been impressed by Toscanini's recording of the work and had submitted his own arrangement for organ to Schirmers. After he made contact with Barber at a musical soirée in 1939, he learned that his transcription had received a lukewarm response from the composer. Strickland, subsequently appointed wartime director of music at the Army's Fort Myer in Virginia, became a champion of Barber's new compositions. He continued to correspond with the composer. In 1945 Barber wrote to Strickland, expressing his dissatisfaction with previously proposed organ arrangements; he encouraged him to discuss and prepare his own version for publication. Strickland, having kept the piece, sent his organ arrangement to G. Schirmer. The company published it in 1949. The recording of the world premiere in 1938, with Arturo Toscanini conducting the NBC Symphony Orchestra, was selected in 2005 for permanent preservation in the National Recording Registry at the United States Library of Congress. Since the 1938 recording, the "Adagio for Strings" has frequently been heard throughout the world, and it was one of the few American pieces to be played in the Soviet Union during the Cold War. The "Adagio for Strings" has been performed on many public occasions, especially during times of mourning. It was: "Adagio for Strings" is the final song on the 2010 Peter, Paul and Mary compilation album "Peter Paul and Mary, With Symphony Orchestra". Mary Travers had requested that "Adagio for Strings" be played at her memorial service. The "Adagio for Strings" was one of John F. Kennedy's favorite pieces of music. Jackie Kennedy arranged a concert the Monday after his death with the National Symphony Orchestra; they played to an empty hall. The concert was broadcast by radio. Barber knew about these memorial occasions. He did a radio interview about it with WQXR and said, "They always play that piece. I wish they'd play some of my other pieces." In 2004, listeners of the BBC's "Today" program voted "Adagio for Strings" the "saddest classical" work ever, ahead of "Dido's Lament" from "Dido and Aeneas" by Henry Purcell, the Adagietto from Gustav Mahler's 5th symphony, "Metamorphosen" by Richard Strauss, and "Gloomy Sunday" as sung by Billie Holiday.
