Two and a half minutes and you're standing in three countries. The whole thing is one violin refusing to sit still, sawing out an American cowboy fiddle line, sliding into a South American tango, then bending into Japanese enka like it grew up there. No plot to babysit, no cast to get attached to, just the instrument as the main character and the arrangement doing all the heavy lifting, which is exactly why the music is the entire selling point here. Then the real story: it aired for two years, vanished, and stayed gone for four decades until the Minna no Uta Hakkutsu Project dug up a surviving copy in 2014 and put it back on the air 41 years later. Slept on doesn't cover it. This was erased, and somebody went looking anyway.
Sasurai no Violin is a single music video made for Minna no Uta, built around the many styles the violin can take. It moves from the fiddle of the American cowboy to South American tango and on to Japanese enka. The video aired for two years and then became lost media. In 2014 the Minna no Uta Hakkutsu Project, an effort to recover missing Minna no Uta videos, found a copy, and the video returned to the air after 41 years.
