Eurovision FACTory

Between 1981 and 1986, Norway and United Kingdom always performed back-to-back. 1981 Norway: 13th United Kingdom: 14th 1982 Norway: 3rd United Kingdom: 4th 1983 Norway: 2nd United Kingdom: 3rd 1984 Norway: 5th United Kingdom: 6th 1985 Norway: 13th United Kingdom: 14th 1986 Norway: 4th United Kingdom: 5th What are the odds of this happening six times in a row, AND in the same order (UK after Norway)?

Both songs called Mata Hari competed when the contest took place in the Netherlands.

There's a weird coincidence with the songs that performed 11th in all three shows im 2022. Those were Croatia, North Macedonia and the Netherlands. Not only were they 11th in the running order in their respective show, they all finished 11th.
