'The King exclaimed repeatedly, "Only one Bach! Only one Bach!" ', (1907). The German composer Bach impresses Frederick the Great with his talent: 'The King next requested him to play a six-part fugue, and Bach extemporised one on a theme selected by himself. The King, who stood behind the composer's chair, clapped his hands with delight, and exclaimed repeatedly, 'Only one Bach! Only one Bach!'.' An episode from the life of German composer Johann Sebastian Bach (1685-1750). From "Story-Lives of Great Musicians", by F.J. Rowbotham. [Wells Gardner, Darton & Co. Ltd, London, 1907]
