This is the song of the junkers (cadets), students of the Guards school. It reminisces how they used to have dates with their girlfriends and drink wine. During the coup of 1917 they defended the Moscow Kremlin valiantly, and they were slaughtered by the attacking Red Army.
This version of the song has somewhat different lyrics. It is from the video game TNO, where this song was chosen by the White Army restoration, whose headquarters was in the city of Vyatka, as their hymn.
Another song about the junkers. Here we see alternating videos of their military service, and also how they used to do dating in the Russian Empire. In my opinion this is how dating should be done. Very sophisticated culture, much better than any dating in the west, such as stupid nightclubs or movie theaters.
