The Viennese Singing Sisters perform 'Memories of Chopin'.
Titles read: "THE FAMOUS VIENNESE SINGING SISTERS IN 'MEMORIES OF CHOPIN'."
Probably Pathe Studio, London.
Act opens with M/S of a painting of Frederic Chopin. Various shots of the six Viennese Singing Sisters singing in harmony; one plays the piano, while the other five stand beside it. I think the tune is by Chopin, the words are in German.
