There's been controversy about the voting in the contest for years. It used to be a "jury" voting in each country until sometime in the 1980s when telephone polling was introduced.
There have certainly been one or two political withdrawals over the years. The contest is usually hosted by whichever country won the previous year (odd exceptions when the same country has won two years running). Several times a country has refused to take part when it would mean attending a country which is not in favor; for example, one or two countries refused to enter when the contest was due to be held in Spain during the Franco period (must have been the '69 contest, as Spain won in 1968).
The 1970 line-up was also a little thin on the ground compared to normal, as several countries decided not to bother entering after the 1969 contest resulted in a four-way tie (the U.K. being one).
I gave up watching years ago when it seemed to me that the music was going downhill the same way as general pop of the time. The last winning song I can recall that I really liked was 1982 -- Nicole for Germany with
Ein Bisschen Freiden.
I say bring back catchy tunes like
Puppet On A String,
Boom Bang-A-Bang,
Waterloo, or for foreign-language entries something like the classic and absolutely fantastic winner
Poupée de Cire, Poupée de Son. Abba was probably the most successful Eurovision act ever. A lot of them you never hear anything about afterwards. Are there any others that were successful?
Well, Cliff Richard sang for the U.K. twice (
Congratulations, 1968 and
Power To All Our Friends, 1973), but he was already extremely well-known at the time. Neither of those won, by the way, although in 1968 we were beaten by just one point!
Bucks Fizz (
Making Your Mind Up, 1981) had a few more hits during the 1980s.
Most of our entries up until the 1970s were sung by people who were already fairly well-known in their own right at the time: Kathy Kirby, Ronnie Carroll, Sandie Shaw, Lulu.....
