The Osam (Bulgarian: Осъм) is a river in northern Bulgaria. Its drainage basin is in between that of the river Vit to the west and the Yantra system to the east. The river has two main tributaries in its upper course: the Black Osam takes its source from the foot of Levski Peak in the Balkan Mountains, at an altitude of 1,821 m (5,974 ft), while the White Osam has its source on the northern slopes of the Kozya Stena peak. In Troyan, the black and white Osam join. It runs north towards Lovech, then north-east until Letnitsa and Levski, where it turns north-west until it flows into the river Danube 5 km west of the town of Nikopol. The ancient name of the river was Assamus.

Zvonko Bogdan (Serbian Cyrillic: Звонко Богдан; born January 5, 1942 in Sombor, Serbia) is an eminent performer of traditional folk songs of Serbia, Croatia, Hungary and Romania.

After a brief adventure in local Sombor theatre, he headed for Belgrade, in age of 19, to enter the drama academy, and started singing in Belgrade kafanas to earn for living, and he found himself in this job.

From 1972, he performed with Janika Balázs' orchestra on Novi Sad's Petrovaradin fortress, a hallmark of tamburitza music.
