Page "The Planets" Paragraph 35

* Two pianos ( duo ) – Holst also created a version for two pianos.

When he was composing the duo, he had two friends play the four-hands version to aid in the transcription.

The two-piano arrangement was published in 1949.

Holst's original manuscripts for it are now in the holdings of the Royal College of Music (" Mars ", " Venus ", " Saturn ", " Uranus ", " Neptune "), Royal Academy of Music (" Mercury ") and British Library (" Jupiter ", " Saturn ", " Uranus ").
