[LIVE 1943] Bidu Sayão in her marvelous La Traviata: "Ah, fors'è lui... Sempre libera"

The great Brazilian soprano Bidu Sayão sings "È strano!... Ah, fors'è lui... Sempre libera", from Verdi's La Traviata, at the Metropolitan Opera in 1943. Her partner is Charles Kullmann. As far as I know, this is her only live recording of La Traviata.
