Paderewski
When Jan Paderewski was to leave his native Poland to play his first recital in London, he asked an influential compatriot to give him a letter of introduction to a leading figure in Britain’s musical world, who might be of assistance should anything go amiss.
The letter was handed to him in a sealed envelope. He hoped that everything would proceed smoothly and he would not have to use it. He did not; his debut was a success and no snags developed.
Some years later, while going through his papers, he came upon the letter and opened it. It read: “This will introduce Jan Paderewski, who plays the piano, for which he demonstrates no conspicuous talent.”
