It's the story that has Britain in uproar*: Cliff Richard and General Franco: the 1968 Eurovision mystery. Did General Franco scupper the judging? Exhibit A: Cliff's UK entry, Congratulations. Exhibit 2: Spain's winning entry by Massiel, La la la. For added measure, exhibit iv: here's Cliff's 1973 entry, which believe it or not also did not win, Power to all our Friends (though Cliff's spectacular moves should not sway your opinion on the controversy* in any way).
