Film of two choirs performing in old Roman Amphitheatre near Paris.
Full title reads: "Paris. Choirs of all nations attract huge crowds to famous old Roman Amphitheatre, still acoustically perfect, the 'Arena of Lutece'".
A small choir perform on a stage built in the ancient Roman Amphitheatre. A large audience are there to hear them. (I can't identify where the choir are from). They get a large round of applause at the end of their song.
Another choir, mainly of men, perform their piece. One of the men hits some very high notes.
