If you appreciate "Adieu Philippine" by Jacques Rozier (his first long feature about youth), you must see "Blue Jeans", a short feature shot 5 years earlier, same kind of story, two young friends on Vespa trying to pick up girls on the south French coast. They both already look like the boys in "Adieu Philippine", not very smart trying desperetly to be funny with girls to get a date. And also already Cuban Cha Cha music. That kind of movie is almost unique document in France. Enjoy.
