The proliferation of this music coincided with a boom in the tourism industry for the island, and Manx music-hall and dance-hall songs and dances saw increased demand. Manx language songs, in particular, benefited from the Gaelic revival from the 19th century onwards. A notable musical episode in the Isle of Man was the imprisonment between 1940 and 1941 of many German musicians of Jewish extraction in Hutchinson Internment Camp on the island. These included Hans Gál (who composed there works for performance by the camp orchestra), Egon Wellesz, and Marjan Rawicz. Though West Gallery music continued into the 1950s, by the 20th century instrumental music accompanied most worship on the Isle of Man. Later in the 20th century, Manx church musical traditions slowly declined. The legacy of immigration, from England and elsewhere, has brought in many new styles of music to the island. Culture Vannin has a dedicated Manx Music Development Team comprising a Manx music specialist, who works with the island's Department of Education, Sport and Culture to encourage the development of Manx music in the school curriculum, and a Manx Music Development Officer, who works to promote Manx music and dance in the wider community. CDs by bands, soloists and Gaelic choirs are produced. The Manx Music Festival is an annual music festival held at the end of each April in Douglas. It was founded in 1892 after music classes were included in the Fine Arts and Industrial Guild, after which the festival gets its colloquial name of "The Guild". Local people and visitors are invited to take part in various singing, instrumental, drama and public speaking classes. At the close of the festival, winners of the individual voice categories compete to win the Cleveland Medal, first donated in 1923 by the Cleveland Manx Society. The first performance of the Manx National Anthem occurred at The Guild in 1907, accompanied by Harry Wood's Orchestra. In November 2014 Culture Vannin, a government sponsored entity, brought together musicians from Norway and the Isle of Man to produce the Norwegian-Manx Collaboration featuring traditional music and providing an educational tour around the Isle of Man. The collaboration featured Manx musicians Tom Callister, Ruth Keggin and David Kilgallon, as well as Norwegian musicians Erlend Apneseth and Margit Myhr.
