Unfortunately, this YouTube video contains no information as to the title of the song, what it is about, or the name of the boy dancing. Thankfully, two of the comments provide some of the information. The song is called “On Cruise Music Plays”, and it’s about a young girl who lives in a small town near to the coast. One day, she sees a cruise liner, and she can hear loud music playing on board where everything seems to be full of life, but she can’t reach it. She dreams that one day the liner will return, and she will be able to board it.
The song is by the Russian duo Olga Zarubina and Sergey Pereverzev, and the boy is miming (very well) to it while dancing. Does anyone know his name?
