Although his son Enrique became an even bigger international star, the elder Iglesias had a pretty successful career that was launched off the back of his appearance on Eurovision. Finishing in fourth place in 1970 after representing Spain with the track "Gwendolyne", the star went on to earn himself a highly successful recording career both in his home country and internationally. He has been regarded as the most successful Spanish singer in the world (yes, even over his son!), having sold more than 100 million records worldwide in 14 languages.
