NEW YORK – The lyricist Irving Berlin once wrote a love song to his favorite musical instrument that included the lyrics, “I love a piano, I love a piano, I love to hear somebody play upon a piano …” He said the tune, dubbed I Love a Piano and debuted in the 1920 Broadway review Stop! Look! Listen!, was one of his best efforts. Berlin wasn’t singing about just any old piano, mind you, but a grand piano.
