Aside from these large-scale works, much of Bush's compositional activity in the 1930s was devoted to pageants, songs and choruses written for his choirs, work undertaken with the utmost seriousness. In his introduction to a 1938 socialist song book, Bush wrote that "socialists must sing what we mean and sing it like we mean it". Under Bush's influence the "music of the workers" moved from the high aesthetic represented by, for example, Arthur Bourchier's mid-1920s pamphlet "Art and Culture in Relation to Socialism", towards an expression with broader popular appeal.
