It was introduced in the film Love and Hisses by Hildegarde and charted by Hildegarde at # 21 in 1943.
The best-selling version of the song was recorded by Nat King Cole in 1954 which reached a peak Billboard position # 7 in 1955.
Although "Je vous aime" is grammatically correct, "I love you" in French is generally said "Je t'aime," incorporating the familiar address "te" rather than the formal (or polite) address "vous." "Je ne sais pas" in the song means "I don't know." "Compris" (or "compree" as it is sometimes phonetically spelled in printed lyrics) means "understand." "Toujours" means "always." "Chérie" means "dear." "Très très fort" means "very very strong."
