Bulba Lives! "Тих бял Дунав се вълнува" ("Still White Danube Undulates") also known as the Botev March, is a popular Bulgarian patriotic song. The lyrics are based on that of a poem by Ivan Vazov titled Radetzky after the steamship seized by the rebels. The storyline recounts a historically accurate incident from the Bulgarian struggles against Ottoman rule, which has earned the status of modern myth for Bulgarians, to some degree due to this song.
