Performances of his own music continued sporadically, but included several of great importance: "The Children of Don" ("Die Kinder der Don") was given five times at the Vienna Volksoper under Felix Weingartner, and three times in Salzburg under Ludwig Kaiser (1876-1932), in 1923; "Bronwen" was first performed in Huddersfield by The Carl Rosa Opera Company on 1 February 1929 and then taken on tour; and the ballet "Aucassin and Nicolette" was performed over two hundred times by the Markova-Dolin Ballet Company during the 1935-36 season. Holbrooke had spent extended periods of time at Harlech, Wales, since around 1915, Scott-Ellis having provided him with a number of residences, and in the early 1920s he moved with his family to a house which he appropriately named "Dylan". In the early hours of 9 November 1928, whilst the rest of the family were in London, fire broke out and the house was completely gutted: Holbrooke sustained serious head injuries and his music library was destroyed. This disaster precipitated a return to London where, having bought back many of the copyrights on his earlier works, Holbrooke set up his own publishing house "Modern Music Library", operating from his various London homes: through this outlet he ensured that his compositions remained available and also issued several printed catalogues of his works.
