The show was broadcasted by the Russian propaganda RT TV Channel in 2014, Censor.NET reports.
"Aleksandrov Academic Ensemble of Song and Dance of the Russian Army was the first to perform the "Polite people" hymn dedicated to the reunification of Crimea and Russia at the Luzhniki stage on May 7, 2016," the RT's official YouTube page reported.
The Tu-154 plane disappeared from radars on Dec. 25 at 5:40 a.m. shortly after taking off from the resort of Sochi, Russia.
84 passengers and eight crew members were on board. The plane was carrying military personnel, reporters of ''Pervyi'' and ''Zvezda'' Russian TV Channels, as well as musicians of the Aleksandrov Ensemble to participate in a New Year's performance for Russian troops deployed in Hmeymim airbase in Syria.
According to the Russian Defense Ministry, fragments of the Tu-154 were found 1.5 km from the coast near Sochi at the depth of 50-70 meters.
''Polite people'' (also known as ''Little green men'') refers to masked soldiers in unmarked green army uniforms carrying modern Russian military weapons and equipment that first appeared during the occupation of Crimea in 2014.
