Dedushka is a song by the Russian act Kanikuly na Marse, and this clip is a short excerpt taken from that track rather than a full recording. Shared on soundboards as an easily replayable piece of music, it circulates mainly because the title and vocal are easy to recognise, even for listeners who do not know the full song. Its short length suits quick edits and reaction posts, where a familiar tune can set a warm, humorous tone in seconds without needing explanation.
