I am desperately looking for the title or any information about a german (maybe french) movie released in the 70's.  The movie is about an orphan who escaped from summercamp to get innocently involved with criminals trying to make him cross a border with a package.  The young boy had just an INCREDIBLE voice.  In fact, I believe the french title for the movie was "L'orphelin a la voix d'or" (the golden voice orphan). One thing is sure, the songs were in german! Thank you for your help!
