"L'amour est bleu" is a song whose music was composed by André Popp, and whose lyrics were written by Pierre Cour, in 1967. Bryan Blackburn later wrote English-language lyrics for it. First performed in French by Greek singer Vicky Leandros as the Luxembourgish entry in the Eurovision Song Contest 1967, it has since been recorded by many other musicians, most notably French orchestra leader Paul Mauriat, whose familiar instrumental version became the first number-one hit by a French lead artist to top the Billboard Hot 100 in America.
