Great Russian song for V-Day commemoration

One of the fairly touching Russian folk songs Farewell of Slavianka is usually played during events to commemorate the country's victory in WWII. The USSR lost some 25 million lives in its Great Patriotic War. From 1918 to 1922, Russia was also bedeviled by a civil war between the Red ('Lenin''s Bolsheviks and allies') and White or anti-Red forces.
