A few years ago in Qingdao (Tsingtao) I taped a street harmonica player giving his version of the famous Soviet song 'Katusha' (Катюша) written by Mikhail Isakovsky.
During the Great Patriotic War the Red Army nicknamed the BM-13 rocket launchers 'Katusha', after the song.
*In case you're wondering, the man attempting to 'sing along' at 1:25 and 2:20 isn't me.
