Dragulji from the history of voting fraud
The year was 1968, the competition was Eurovision, and we do not necessarily have to believe the Guardian's assurance that this or any other song by Cliff Richard was "actually one of the better entries." But its second place finish may not be valid evidence one way or another. Because apparently what happened was that old Francisco Franco sent the representative of Televisión Española around Europe to funnel money to other television and publishing outlets, buying up series, arranging for concerts and promotions, the works. This infusion of cash translated into a phalange of votes for the Spanish entrant, a very serious (oh, let's quote the Guardian again: "trumpet-tootling, bodice-ripping") song by Massiel called "La la la." Of course there is a video. And another. Rock out to the vote-buying, boys n gals.
