At Arthur Rubinstein’s farewell performance at the Usher Hall in Edinburgh, 1976, when a hush of pure reverence preceded the applause after the nearly-blind old maestro’s rendition, the ghost of Chopin, who coincidentally had given one of his last performances as a pianist in the very same hall in 1839, stood by his side, brandishing a handkerchief.  I know: I was there.

     Or it could have been the accompanist, holding the score?

     No. Definitely Chopin + hankie.

     Shortly thereafter, Rubinstein (above), aged 90, after another farewell tour, eloped from London with his 60-year-younger secretary to Geneva, where he died five years later. His ashes were scattered in Jerusalem.  (Hear Rubinstein play Chopin's Andante Spianato and Grande Polonaise Brillante here.)

    Another ancient genius, Jorge Luis Borges, followed an oddly similar late-in-life trajectory, in his case from Buenos Aires, accompanied by his young Japanese secretary and wife-to-be, from whom he may well have finally had his first roll in the hay, a no doubt prolonged and rather creaky encounter that couldn’t have been much fun for Señora Borges; but the point was made, he died fulfilled.

      Or, at least, in Geneva.
