My 3-year-old Nephew's Singing Prowess

My nephew is really into singing. Even if he's doing something, he follows to the tune of this song. I bet this kid will go a long way if he will pursue a career in singing, in the future.

I don't really know how to speak polish. Although I know a few words because my brother-in-law, who is his father is Polish. According to his dad, this is a love song. It is entitled Zono Moja by Ivan Komarenko.
