From the wiki: “‘Strangers in the Night’ is credited to Bert Kaempfert with English lyrics by Charles Singleton and Eddie Snyder. It is sometimes claimed that the Croatian singer Ivo Robić was the original composer of ‘Strangers in the Night’ (performed as ‘Stranci u noći’), and that he sold the rights to Kaempfert after entering it without success in a song contest in Yugoslavia. These claims have not been substantiated.
“Robić, a pioneer of popular Yugoslav music from the early 1950s on, was the only artist from Yugoslavia whose records were available in the record shops of Europe and the rest of the world. He performed and collaborated with Kaempfert, Freddy Quinn, and Dean Martin. Robić would go on to record Yugoslav and German versions of ‘Strangers in the Night’, ‘Stranci u Noći’ with lyrics by Marija Renota and ‘Fremde in der Nacht’ with lyrics by Kurt Feltz.
“Kaempfert originally recorded the melody under the title ‘Beddy Bye’ as part of the instrumental score for the movie soundtrack to A Man Could Get Killed, which went on to win a Golden Globe Award in 1967 for Best Original Song in a Motion Picture.
