Take On Me by A-Ha was a huge hit in the 80’s, and still has that retro feel and sound. When played in movies or TV, the song is usually a homage to the past, so it’s not surprising North Korean students from Kum Song School, Pyongyang would be playing the hit. They’re stuck in a time warp in the past. Of course, their skill and accuracy is near perfect as the totalitarian government wouldn’t allow a non-perfect rendition to leak and embarrass the state.
