It is a 'song contest' - even if people feel it has morphed into a game of political one-upmanship.
The original idea of the Eurovision Song Contest was a contest for song writers, in order to build some cultural bridges between European nations after the war.
Mr Anderson and Mr Ulveus had a number of attempts to write Sweden's entry before they were successful - some for groups in which they were not personally involved.
Because for them, they would 'win' as songwriters no matter who actually sung their song.
And in 1974, they did - and the rest is proverbial history.
