Don Cossacks are a troupe of men dressed in Cossack style who sing an unaccompanied traditional song. They are presumably rehearsing for some kind of show. It is a very rousing song. They are presumably practising on a rooftop. There is one row of seated men who have their legs crossed showing their attractive black boots. The two rows behind stand. They all wear nice Cossack hats. An unusual male voice choir. Their song includes yelps, whistles and other funny noises. Very nice little film - some of them look as though they are really enjoying themselves.
