The great composer of The Planets, Gustav Holst also taught himself Sanskrit, lived in a street of brothels in Algiers, cycled into the Sahara Desert, and allied himself during the First World War with a ‘red priest’ who pinned on the door of his church “prayers at noon for the victims of Imperial Aggression”. He hated the words used to his most famous tune “I Vow to Thee My Country” because it was the opposite of what he believed, and died before the age of 60 – broken and disillusioned.
