Croatian singer Kruno Slabinac performing "Tvoj Dječak Je Tužan" ("Your Boy Is Sad"), the Yugoslav entry at the 1971 Eurovision Song Contest. A very interesting entry with a truly contemporary arrangement for its time (it's even vaguely reminiscent of prog-rock) and a powerful performance by Kruno, it was however a song very un-characteristic and downbeat for the contest's standards (like almost all of the Yugoslav entries in the 70s), and as a result it (like them) fared quite poorly at the voting. Note: The composer of this song is Ivan Krajač, who had already represented Yugoslavia in 1969 as a performer (labelled just "Ivan") and would also write the lyrics for their 1972 entry.
