Giraud's demo was gathering dust with publisher Claude Pascal when an Italian agent picked it up for newcomer Ivana Spagna. When that version was out, Alain Milhoud cut it on his (English speaking) Spanish band Los Pop Tops. That's when Pascal woke up, smelled hit potention and decided to launch it big style in France (in two versions). The Pop Tops version was even stalled a while.
