Instrumental theme in gangster spoof A Man Could Get Killed, starring Melina Mercouri. Soon provided with words by Charles Singleton & Eddy Snyder and recut by Kaempfert in '66 as Strangers In The Night, still an instrumental.
Jack Jones [first vocal version as Strangers In The Night, crediting Charles Singleton/Eddy Snyder for the words]
Frank Sinatra [idem; n°1 US, UK & B; Frank hated this song; according to baroness de Selys Longchamps, the mother of Delphine Boël, the song that forged her relationship with prince Albert of Belgium; for a second link between Bert Kaempfert and the Saksen-Coburgs, see: New Year Rock]
Hervé Vilard [as Etrangers dans la nuit]
Ivo Robic [as Stranci U Noci and as Fremde in der Nacht]
Michel Louvain [als Plaisir de la nuit]
Bill Van Dijk [as Vlinders In De Nacht]
The real author might have been Avo Uvesian, his original title Broken Guitar, outvoted by Frank Sinatra. Fearing he might lose US copyrights Uvesian made a deal with Bert Kaempfert.
