"Bye Bye I Love You" was the Luxembourgish entry in the Eurovision Song Contest, in which year, the song is notable in the history of the Contest; it was the very first entry composed by Eurovision veteran Ralph Siegel, who would go on write 19 ESC entries throughout the 1970s, 1980s, 1990s and 2000s, 1 for Switzerland, that participated in the Eurovision Song Contest 58 times?
Bye Bye I Love You "Bye Bye I Love You" was the Luxembourgish entry in the Eurovision Song Contest 1974, performed (despite the English of the title, although the title phrase is in that language) in French by German-British singer Ireen Sheer. The song is notable in the history of the Contest; it was the very first entry composed by Eurovision veteran Ralph Siegel, who would go on write 19 ESC entries throughout the 1970s, 1980s, 1990s and 2000s - 14 for Germany including 1982 winner "Ein bißchen Frieden", 3 for Luxembourg, 1 for Switzerland, Montenegro in 2009, The Social Network Song for San Marino in 2012 and most recently "Crisalide (Vola)" for San Marino in 2013.
Refrain (Lys Assia song) "Refrain" was the winning song of the Eurovision Song Contest 1956, co-written by Émile Gardaz and Géo Voumard, performed by Lys Assia representing Switzerland. It was the first-ever winner of the Contest, but not the first-ever performance by Switzerland. This apparent anomaly is due to the rules of the 1956 Contest allowing (for the only time to date) each competing country to be represented by "two" songs. Assia represented Switzerland singing both songs (one of only two performers to do this), and had previously performed "Das alte Karussell" in German ("Refrain" was sung in French).
