"Toi" (English translation: "You") was the Luxembourgish entry in the Eurovision Song Contest 1975, performed in French by Irish singer Geraldine. The entry had a high pedigree, being penned by three authors/composers who had all written/composed previous Eurovision winners. Pierre Cour had been partly responsible for the 1960 winner "Tom Pillibi" and Bill Martin and Phil Coulter had created the 1967 winner "Puppet on a String".
The song is a ballad, with Geraldine telling her lover that "my life doesn't exist without you" and pledging her unending love to him. Geraldine recorded the song in two languages; French and her mother tongue English, the latter as "You".
Another singer with a similar name, Géraldine, represented Switzerland in the 1967 Eurovision Song Contest in Vienna, finishing last with 'nul points', but as John Kennedy O'Connor's The Eurovision Song Contest - The Official History notes, despite the similarity in name, the two singers are unique. This Geraldine later married the song's composer, Phil Coulter.
