This guy in Croatia took three years to record this music video, and it's still only two minutes long. But he gained a full head of hair and a viral video. He most likely ended up hating the song, though.
The song is "Halo, Džozefina" (Hello Josephine) by Đorđe Marjanović, who was a star in Serbia (Yugoslavia) in the 1950s and '60s. -via reddit
