I've just looked at
I wonder if the points of Yugoslavia should be splitted to the seperated countries...The same for Serbia & Montenegro.
I've just looked at the complete list of scores for Yugoslavia 1961 to 1992 on the
Yugoslavia page of the Eurovision website. That just lists all Yugoslavia's appearances as one list, no matter which present day constituent (Croatia etc.) the artist came from in a given year. However page 192 of the book
The Eurovision Song Contest 50 Years The Official History - John Kennedy O'Connor lists Yugoslavia's entries as Yugoslavia (Bosnia-Herzegovina), Yugoslaiva (Croatia), etc. I've looked at that page of that book to group together the years in which Yugoslaiva's artist came from Bosnia & Herzegovina, Croatia, etc. as follows. Each year is accompanied by the end-of-contest points total, and I've calculated a total for each constituent. As you can see, the totals vary considerably, partly helped by 11 Yugoslav entries were from Croatian artists, whereas only one was by a Montenegrin artist.
Bosnia & Herzegovina
1964(0), 1965(2), 1973(65), 1976(10), 1981(35) TOTAL 112.
Croatia
1963(3), 1968(8), 1969(5), 1971(68), 1972(87), 1983(125), 1986(49), 1987(92), 1988(87), 1989(137), 1990(81) TOTAL 742.
Montenegro
1984(26) TOTAL 26.
Serbia
1974(6), 1982(21), 1991(1), 1992(44) TOTAL 72.
Slovenia
1961(9), 1962(10), 1966(9), 1967(7), 1970(4), 1975(22) TOTAL 61.
Adding these constituent totals to the totals of present day Bosnia & Herzegovina, Croatia etc. is wrong on two counts:
1) No matter which part of Yugoslavia the artist came from in a given year, from 1961 to 1992 the song represented the whole of Yugoslaiva, not just the applicable constituent. For example, Yugoslavia's only victory in 1989 still belongs to Yugoslavia, not Croatia.
2) Even though Yugoslavia's national selection could feature contestants from different Yugoslav contituents, Yugoslavia could still only have one song in the ESC 1961 to 1992 (just like Greece, France etc.). In all those years Yugoslavia did NOT have a special privilege to send five separate songs (one by an artist from each of its five constituents), whereas since the break-up present day Bosnia & Herzegovina, Croatia, Montenegro, Serbia and Slovenia can all send separate entries.
For statistical purposes you need to list Yugoslavia's total and the post 1992 derivative countries' totals separately. As far as Eurovision is concerned, Yugoslavia existed up until 1992, the others didn't exist then. From 1993 the other derivative countries have existed (Serbia & Montenegro split after ESC 2006) and Yugoslaiva no longer exists.
Likewise Serbia & Montenegro should be kept as yet another separate country. I know it was short lived, with just two entries 2004 and 2005 (they voted but didn't sing in 2006), but you can't add those scores to either Serbia's total or Montenegro's total, nor Yugoslavia's total.
