Maria Callas singing Habanera aka "L'Amour est un oiseau rebelle."
French and English lyrics from Wikipedia.
The image is from Wikipedia, where the following caption is displayed: A slim Maria Callas as Violetta in Giuseppe Verdi's La Traviata at La Scala, 1955. Maestro Carlo Maria Giulini said of these performances, "Reality was onstage... Only that which transpired on stage was truth, life itself."
That quote from the Maestro blows me away.
