While fishing aboard a boat one day with his friend Frants Beyer, Edvard Grieg was struck by a novel musical theme. He quietly scribbled it on a piece of paper and set it down beside him. Some time later the note was blown overboard by a gust of wind and, unbeknownst to Grieg, retrieved and examined by his companion, who momentarily began to whistle the tune. "What was that?" Grieg asked. "Oh, just an idea I had," Beyer nonchalantly replied. "What the devil!" Gried exclaimed. "I just had the same idea myself!"
[Early retirement? Such was the extent of his success that Grieg was awarded a state pension in 1874 -- when he was twenty-nine years old.]
