In 1973, the year before the centenary of the birth of Gustav Holst, a composer much admired by Strutt, inspired the production of a symphonic poem entitled "Pluto, the Bringer of Change". This was intended as both a tribute to the memory of Holst and a commemoration of his birth, and the intention in performance terms was as a work to be played in the same programme as Holst's "Planets" suite – the orchestration is the same, except that no vocal forces are used. The compositional history of the piece is, however, not of a work originally composed for orchestra, but of a work transcribed for orchestra from a chamber piece for seven clarinets. This clarinet septet – the scoring included the rare octocontrabass and contrabass clarinets, as well as the E-flat piccolo and alto clarinets – was played in a private run-through at Kneller Hall (the Royal Military School of Music) by an ad hoc ensemble led by Terry Busby in 1969, but subsequently ceased to have a separate existence once the orchestral transcription had been made.
