Luxembourg was represented by 17-year-old Greek singer Vicky Leandros ( billed on the night simply as Vicky ) , with the song ' " L'amour est bleu " , at the 1967 Eurovision Song Contest , which took place on 8 April in Vienna . The song was chosen internally by broadcaster RTL . " L'amour est bleu " finished only fourth in the contest , but went on to become one of the most globally successful and instantly recognisable melodies ever to come out of Eurovision . An instrumental version of the song ( " Love Is Blue " ) recorded by French orchestra leader Paul Mauriat topped the United States Billboard Hot 100 for five weeks in early 1968 , becoming one of the year 's biggest-selling US singles , and also went to number 12 on the UK Singles Chart . The song has since been covered a multitude of times in both vocal and instrumental versions and is classed as a standard , although most are unaware of its Eurovision origin
