 In the same year, Delius began a fruitful association with German supporters of his music, the conductors Hans Haym, Fritz Cassirer and Alfred Hertz at Elberfeld, and Julius Buths at Düsseldorf.Haym conducted "Over the Hills and Far Away", which he gave under its German title "Über die Berge in die Ferne" on 13 November 1897, believed to be the first time Delius's music was heard in Germany.In 1899 Hertz gave a Delius concert in St. James's Hall in London, which included "Over the Hills and Far Away", a choral piece, "Mitternachtslied", and excerpts from the opera "Koanga".
