Also known as Who's That Singing Over There?, this bittersweet 1980 comedy was released in its native Yugoslavia as Ko To Tamo Peva. The time is 1941: a crowded bus travels over unpaved Yugoslavian terrain. In the manner of
Stagecoach, the audience comes to know and grow fond of the various passengers: the lovers, the politician, the eccentrics, etc (each character is played by a well-known Yugoslav movie personality). The film's genial mood is unexpectedly shattered when a Nazi bomb scores a direct hit on the bus. The only surviving passengers are a pair of travelling gypsy musicians--hence the film's title. ~ Hal Erickson, All Movie Guide
