Kapustnik
Kapustnik (, which could be translated in English as "Cabbage festival") is the Russian tradition of celebration. Generally, it is a medley of well-known songs, in which all the lyrics have been changed to celebrate (or poke fun at) the guests of honor. A typical Kapustnik may have several scenes, lasting approximately 10 minutes, and is performed by one or more singers/actors with piano accompaniment, or karaoke-style playback.
