So one of the top three in the odds has I think won every year since about 2012? 2011 was a big miss I think in that regard (France were at LESS THAN EVENS that year, so little wonder that the French delegation were basically openly planning the 2012 contest in the last couple of days before...), and I think 2001 was as well, and definitely 1994 - so generally I'd guess the bookies flunk it about once a decade.
They usually tend to get it right, but I think this year is one they'll be off - I mean, Italy are down to 5/2 with France behind at 3/1 on Betfair, which just feels *insane* to me when Iceland are at about 16/1.
