Park Café — Monsieur

Luxembourg was represented at the Eurovision Song Contest 1989 with the song "Monsieur", written by Maggie Parke, Gast Waltzing, Yves Lacomblez, and Bernard Loncheval, and performed by the band Park Café. The Luxembourgish participating broadcaster, the Compagnie Luxembourgeoise de Télédiffusion (CLT), selected its entry through a national final, after having previously selected the performer internally.
