Full titles read: "Pathetone presents - Joan Revel and Mario de Pietro - the well-known Soprano and Instrumental ----." (title obscured by timecode.)
London (probably Pathe Studios).
Various shots of soprano Joan Revel, in Spanish traditional costume, singing 'La Paloma'. She is accompanied by two men; one on guitar (presumably Mario de Pietro) and the other on the accordion. The Pathe Studio is decorated as a Spanish terrace - ole! (Soundtrack continues for another 6 seconds after visuals cut out - no singing is missed.)
