1937: On 24 October, while riding in wooded country on Long Island, in New York State, Cole Porter’s horse shied and fell on him, crushing both his legs. For the rest of his life, Porter was crippled and in constant pain. Typically, the composer of a host of light-hearted lyrics invented names for his severely damaged limbs: Josephine and Geraldine. Josephine, the left leg, was sweet and obliging; Geraldine, the more painful of the two, was “a bitch, a psychopath”.
